Nokia 6230i

dont actually remember all...

from new to old:
samsung galaxy s2

and the other ones...dont remember

Samsung D900
Nokia 5800

That's all I've ever owned.

Sony J70
Ericsson T65
Sony Ericsson T610
Sharp GX-30
Sharp GX-29
Sharp 770SH
Sharp 880SH
Eten X500
Nokia 5800
Motorola Defy

The T65 was the Chuck Norris of phones, simply undestructable. The 770SH was pure hot sexyness. Still one of the best looking phones out there for me with the black screen and body and silver aluminium keyboard. I don't know which of them gave me the best experience in their era, but it's probably the Defy, cause it's the first time that everything works as expected on a phone.

(Don't worry if you don't see any logical pattern in it as there ain't one)

Ericsson (can't remember the model as it was like 10 years ago...
Nokia 3310 Snake
Sagem My X2 It had a colored screen and some stupid puzzle games...
Sony Ericsson k610i This was one helluva phone...
Nokia 5310 XpressMusic
Nokia C6-00 (current) (it should have been a HTC Desire, but it was out of stock, and they "couldn't" order one...)

E: There is only a picture of Sagem (link) because the rest are more or less popular phones (or were popular phones)

Nokia 3310 (Snake)
Nokia 3330 (Snake 2!)
Nokia 7210 (Colour screen!)
Sony Ericsson 880i
Samsung D900 (Great phone, but too distracting - always flipping the phone up and down)
Sony Ericsson W380 Walkman Phone (Pretty cool, till the OLEDS on the outside burnt out, and you couldn't see who was calling until after you answered the call...)
LG Cookie (Touchscreen was annoying)
HTC HD 2 (Couldn't get rid of it fast enough.... buggy Windows 6.5)
HTC Desire HD (Amezzzin')

From now on, I suspect it's going to be a long trend of HTC phones (on Android).
