This phone has everything that a 3G phone needs. Since everybody highlighted all gud features, lemme point out some cons of this phone.
1) The audio quality is not as good as W550i(trust me) . 2) The megabass really sucks when u compare with W550i
.3) Even the external volume is much less compared to 550i.
4) Just chek out the stereo widening in 550i and 850i. u il feel the difference.
5) Camera quality is not so great as in k750i. Nightmode shots are really bad.
6) Walkman 2.0 differs only in UI. Not much difference.
7) Edge is missing in this phone. but 810 has it.
8)With 2 MP camera video resolution is just 176*144 which is really bad. Video quality isnt gud either.
9) doesnt support AVI video.
10) How the hell did SE forget the camera shutter? and dual flash cud have been provided like w710i
11) Body not at all rigid. Cud have been bit rigid and stylish .Just look the back view of 850i, which is pathetic.
12) No auto focus and macro mode as in K750i and W810i
13) It would have been better, if handsfree had display and control for FM and walkman .
*Now some damn gud features*
1) Supports WMA, Realmedia files unlike other walkman phones.
2) Has a separate video player
3) Advanced Photodj is damn gud
4) The top 2 buttons near the screen are really useful especially in standalone. Also u can use for navigating thru menus, if u feel keypad isnt comfortable
5) Juiced game is really cool
6) U can Blog photos taken
7) Rss feed is an impressive feature
8) 5 different alarms too gud
9) dedicated key for shortcuts and walkman(but walkman key not really comfortable)
10) bluetooth transfer rate of 40kbps
11) Preview contents downloaded from Playnow before purchasing
12) Track id is ultimate feature.
13) Supports stereo bluetooth
14) Highly improved File manager
15) Next word Prediction while typing sms will be really usefull for frequent sms.
16) Extremely gud screen resolution. Screen is crystal clear and colourfull but needs some more brightness.My final suggestion would be, This phone is really gud but to me the price seems too costly. I dont feel somehow the phone is worth 20K+. If you guys are really interested in this phone pls wait for a couple of weeks. The prices are slashing down rapidly. when the price comes to 17-18K u can go for it. Or else SE is launching its next 3.2MP Cybershot walkman phone in a couple of weeks. the looks are damn gud. The best I have seen so far. Hope the price is not more than 23K. It has edge, camera shutter, image/video stabiliser . So go for this phone better.
