I read a lot of the reviews and carefully researched this phone. I also visited a Circuit City to see the phone in person. As a OS X user, bluetooth and iSync support was mandatory. Also, I wanted to play games, surf the net, AIM, take photos and email then, etc. This phone is bigger then a Sony Ericson, but after holding the new Sony's in my hand, I find them way too small. I can;t imagine using that phone for anything other then a phone. The screen is way too small compared to the 3650. The 3650's screen is perfect. The dial pad is awkward the first week, then it's second nature afterwards...Pro's1)Sybina OS2) play games on nice size screen3) email/surf on nice size screen4) great features and sound5) bluetooth6) can run applications7) headset speaker phone feature8) blue keypad lights are cool9) camera is half way decent10) painless syncing with iSync via bluetooth11) Holds more address info when addresses are synced from X's Address Book12) Reads and displays AIM personal buddy photos when taken from X'sAddress Book13) Can get opera browser to surf withCon's1) keypad takes a week or so to get used to2) only comes with 2 games (more of a whine)3) Aren't many apps for the OS yet4) A lot to learn, gotta read the manualIt comes down to what you want from the phone. If you want small slick Zoolander type phone, get a Sony-Ericsson. If you want to surf the net, play games, take notes, make shopping lists, AIM, etc you really want the 3650. The SE may do those, but it's a joke on the SE's small screen compared to the 3650.
