well... I guess I remember all my phones I owned
Nokia 1100 (l liked the snake game)
Sony Ericsson T226 (had good morphun games and my first color screen phone)
Nokia 3300 (I liked the qwerty keyboard and music)
Sony Ericsson k310 (has all the basics needed in the time, but low memory capacity)
Sony Ericsson K750 (also the memory capacity and awesome camera)
Sony Ericsson w810 (nice in every way... nice upgrade from k750)
Sony Ercisson w200 (because it was cheap and I've lost the w810 also I use it for like 5 years and combined with an ipod touch)
Sony Ericsson w760 (I am using it when I play old j2me games... also best phone design for me)
Sony Ericsson Xperia Play (nice start for android and emulators had to replace the flex like 3 times... actually working)
Sony Xperia S (it used to be really good... but now I see it has many flaws)
Sony Ericsson Xperia Pro (loved the keyboard, actually is my second smartphone)
Sony Xperia U (bought because it's small, actually broken)
Alcatel C5 (Just because of the analog tv incorporated... I use it sometimes)
Sony Xperia Z1 compact (really nice smartphone, bought because actually the phones tend to grown in size... and was the "smallest" and powerful in the time)
Sony Xperia Z5 Compact (it tends to get hot... that annoying sd810... but learned to control temperature... and I could play several dolphin games at full speed... it's my third phone)
Domino DM98 (actually I got tired of smartphones because they are getting bigger and bigger... so I own and android smartwatch and I am really enjoying it)
I could go back to smartphones if they design them with small screen (under 3,5 inch) never liked the way smartphones gets bigger and bigger and all of them look the same brick thing... also I miss those with qwerty keyboard or those experiments like the xperia play.
