My first, i think, was a Siemens A40
Then i got a SonyEricsson, i don't remember the model, it had a low screen resolution (somthin like 170x60 i think), capable of 8 shades of gray i think
Then my first smartphone a Nokia 3650, i had it for quite some time, then the screen glitched and my father had another one laying around and gave it to me.
Then i got a N73, black one but with internet edition keys, i jailbroke it and installed lots of **** in it, it had this nasty bug where there was some sort of permanent memory leak, after installing and uninstalling enough programs you run out of memory, and since the RAM is actually more like virtual memory once you run out of disk space you also run out of RAM, so i had to stop trying new progs after a while, luckilly things only started to get real bad after i already had most of the stuff i wanted.

I was about to get myself a N78 or N79 when i learned about the coming of the N900, it made me give up on getting one of those and start saving for a N900. Before the N900 i had swore i would never get a mobile with moving parts (slide, flip, twist etc) afraid i would endup wearing down the mechanism or break when it fell, but after learning about the capabilities of the N900 and reading some reviews i changed my mind.

5800
before that was n95-8gb
n95 being the best phone i've ever used.. i wonder why :-/

HTC Hermes (Orange SPVM3100)

Used to flash cutom roms onto it every week

But... it ran Windows mobile... so not very good really...

Personally, I replaced an N95 with an N97 mini, and S60 5th Ed disillusioned me so much that when it was accidentally destroyed by being run over by a tram I decided that since I didn't like any of the Android hardware solutions and the N8 was still a bit expensive for me, I'd give the N900 a try.

And I'm loving it.

I had an E51 for about two years, really liked it.

However, last summer my then-girlfriend told me I should get a N900, and a little latter she accidentally poured pineapple juice on my the E51.
