That Nokia music player and a couple of the Nokia phones I still have lying around somewhere. Another 10 years I could send to a museum 
To be fair, the Captivate was a cut-back version of the original Galaxy S⦠so it was fair to call it something a bit different.
Now that was a terrible phoneā¦

Ah your list looks very similar to mine, I just gave up last night trying to find them.
The C12 you could āchipā so every time you turned it off and on again it topped itself up Ā£5 
I wouldnāt even wanna think pre iPhone haha.
Saying that thought I guess my first smart phone was actually the Nokia N95
Sony Ericsson P800 & P900
HTC Kaiser and other models on the Windows Mobile platform
Nokia N95 (Had 3 returned them all)
Loads of Blackberries
Then I got this bad boy on day one UK Launch
I had a plethora of dumbphones/feature-phones which I donāt care to remember.
My first smart phone was the Sendo X back in 2004. This was a brilliant phone running symbian, and I was really looking forward to the X2, which was unfortunately never released as Sendo went bankrupt when in partnership with Microsoft to develop the first Windows Mobile smartphone (which was eventually released as the HTC Canary).

Next up was the Virgin Mobile Lobster 700TV in 2006. I bought this only because my Sendo X died (microphone broke). It ran Windows mobile, and contained a DAB radio, which work ok although was useless on the move. The key selling feature however was that it could receive IPTV over the DAB network, a feature that was sadly discontinued (because it was expensive and pretty rubbish).

2008 brought me the HTC Touch Diamond, again another windows mobile smartphone. This was a massive step up from the Lobster, and actually felt like a high quality phone. The resistive touch screen was annoying though, so it worked best with the stylus (Iād got used to this from using a Dell Axim PDA). First phone I installed custom firmware on 

At this point I switched to Android with the HTC Hero in 2009. It had a weird chin at the bottom of the handset, which contained a trackball which glowed. It worked surprisingly well for navigation (in addition to a capacitive touch screen). This phone was subject to multiple custom roms and was eventually sold on ebay.

Next up in 2012 was the Motorola Atrix 4G, this first mainstream phone (I believe, and certain beating the iPhone) to have a fingerprint reader. Interestingly Apple bought the company that manufactured the fingerprint reader in the Atrix 4G (AuthenTec) which lead to them developing their own fingerprint readers for the iPhone. The Atrix 4G had a feature called āWebTopā, which essentially meant you could connected it up to a dock, or a monitor and it would switch to an embedded cut-down version of linux, where you could āsort ofā run real desktop applications, and view the phone in a little PIP view. It had a separate mini HDMI output to allow this, and could also double up as a fullscreen media player via HDMI if you didnāt want the full linux desktop experience.

My current phone, now on itās last legs due to a failing battery after 4.5 years is the LG G2. The length of time Iāve had this phone is a testament to how good I think it is. itās been through 4 major versions of Android, either with official firmware or LineageOS. It has however had the mainboard replaced, after the SOC suffered a catastrophic failure that meant it would fail to start up even in engineering mode.

At the moment Iām struggling to find a phone to replace this with, that will last anywhere near as long as this, at a similar price point (it was only Ā£300 SIM free at launch).
Interesting thread. Iām way behind everyone here, I didnāt get my first mobile phone until 2009, and it was an old Nokia dumb-phone someone gave me. I spent a few more years with a couple more discarded feature phones, though in 2011 I bought an iPod touch 4th generation which I carried around everywhere with my phone. I upgraded to the 5th generation the following year, so had a sort-of smartphone with dumb phone+iPod touch.
I finally got a proper smartphone when I bought a second-hand iPhone 5s in September 2015. And I managed to break it over Christmas and upgraded to an iPhone SE which I love. Though my favourite form factor is still the iPod touch 5th generation ā I wish Apple would make an iPhone that thin.
I didnāt really get into the whole smartphone thing until I got a Blackberry Bold 9700. It was both terrible and excellent at the same time. It couldnāt maintain a constant mobile connection but at the time, typing on the keyboard felt AMAZING.

I then went through the following in order of ownership:
- iPhone 4 (Black)
- iPhone 4s (White)
- iPhone 5 (White)
- iPhone 5s (Space Grey) & Nexus 5 (Black)
- iPhone 6 (Space Grey)
- iPhone 6s Plus (Space Grey)
- iPhone 7 Plus (Jet Black) & Samsung Galaxy S7 (Black) owned very briefly.
Iām now using the iPhone X (256GB) in white and itās by far my favourite phone, ever. I absolutely adore this thing.

This little beauty was my firstā¦
After that went from iPhone 3GS to iPhone 5, 6S now iPhone X!
Thankfully never suffered a phone without a qwerty keyboard 

First was this thing, then
HTC Wildfire
HTC Nexus One
HTC One S
Nexus 4
Sony Z1 Compact
Moto X2
Nexus 5x
and now iPhone 7
(thatās a lot of phones)
Sony Ericsson Z530i DaVinchi Code Edition

Then
iPhone 3GS
iPhone 4S
iPhone 5S
iPhone 7Plus
and now iPhone X (and I love it)
Nokia 3310 (Snake II or Space Impact ??)
Nokia 1108
Motorola L6
Sony Ericsson W710i
Nokia N95
Sony Ericsson J10i Elm
Samsung Galaxy S2
Nexus 5
Nexus 5X
Pixel 2

Donāt be jealous. 
I still have one of these for emergencies. Battery lasts forever, and is practically indestructible.

Does this count @simonb 


Used it to load cash onto my Mondex card when I lived in Swindon back in the mid 90s.
Nokia 3220:

First phone ever! Was a real head turner when I was a kid, crazy loud, built like a brick and had bright flashy sides
Still got it in a draw somewhere, Iām sure itāll still work 
Sony Ericsson W300i:

Loved it, had bluetooth and IR (yep, IR, for sending mp3's and wallpapers to friends
) Loads of storage, probably a good 128MB or so!
Fantastic device for listening to music, had all the controls right on the side with a fantastic display on the top too 
Nokia 6600 Slide

Yep!! Nokia makes a return (not the only one either) The screen was giant compared to the W300i, the keypad was nice and the buttons looked super vibrant. It survived many a drop, including one down 3 flights of stairs
but it lived to fight another year or so 
Nokia 5800 xpressmusic:

This phone was superb! First of my many smartphones
Running Symbian OS, with a beefy resistive touchscreen (and a stylus!) it was wonderful, the screen got broken a few months in, in order to repair it took well over an hourā¦
Lots of layers folded over each other, all intertwined, etc. But a fantastic phone which did everything I wanted it to do (at the time) being able to watch YouTube and have a device which connected to WiFi was almost magic 
LG Optimus One:

Well this was a great phone, it slowed down very quickly!! But it was awesome up until that point
Android for the first time, apps, limited storage and a mediocre camera⦠But I loved every second of it
The battery was excellent and live wallpapers were the hit thing
Freedom to do everything better than the guys with their iPhones was wonderful too
⦠Widgets anybody 
HTC ChaCha:

Hated it. It was a side-grade at best⦠The Optimus One became unusable and this was the only option I had at the time, it didnāt stick around for long Iāll tell you that! Probably the worst device Iāve ever experienced ⦠Even including the iPod Touch 3rd Gen I had
Yes, even Android fanboys are tempted by Apples sometimes haha! I learned my lesson though
Straight back to Android afterwards!
Nexus 4:








This is the best device to have ever existed. Hands down. The endā¦
The way the glass rolled over the edges, the feel in the hand, the phenomenal design and the eye-catching rear panel
I was in love with Nexus, Google, Android, the 4! I sold this to buy a Nexus 5 (shouldnāt have bothered⦠But hey ho) I actually bought a new Nexus 4 a little over a year ago - Turns out the seller was a liar but had gone to the effort of Bootloader unlocking, signing in a generic account then turning it off⦠VACUUM SEALING the box and selling it as brand new on Amazon⦠#massivecomplaint!!
So I sent it back and never looked for another 
Still remains my favourite device to date, even if it is slow as! 
(The order is going to be very obvious hereā¦
)
Nexus 5:
It was alright, felt cheap and I didnāt miss it tbh 
Nexus 6:
This was huge! Pretty much as big as the Nexus 7 I had, which up until getting the 6 was a device I carried everyday haha!
Nexus 6P:
Disliked it⦠The sharp edges, the meh quality and the later battery depleting issues!
I wasnāt in love with it from day 1 but it wasnāt as bad as the 5 
Pixel XL:
It was the device I liked most (after Nexus 4 ofc
) It was light, looked great (IMO) and performance was awesome!!
Pixel 2 XL:
Might it replace the Nexus 4 as my favourite Google device?! No⦠But itās my favourite of the Pixelās
Google shouldāve done this first time around!! But I do love it and I cannot wait to see whatās next! 
Some more history, I started out normally with the Nexus 4 but rather quickly went down the modding route
Unlocking bootloaders, flashing everything I could see. After a lot of different ROMs, GAPPS and Kernels later (not to mention recovery, TWRP won that battle though) I eventually settled on Cyanogenmod + Franco Kernel
nothing could top it, battery was well over a day, performance was untouchable and the beauty of the customised experience was great!
From there I did the same until I got to the 6P, where I only bothered with flashing kernels. I liked what stock android had to offer but loved what Franco was doing, Iāve not flashed a ROM for years but I still run unlocked BLās and now Iāve got Magisk running on my devices 
Ericsson GH388. That was a really smart phone. Then I got an Ericsson GH688.
I loved this phone. It served me well until my iPhone 3G.
