Video playback is superb! Tv quality.
3D Gaming is great
Support for .doc and .pdf and spread sheets
Battery life is comparitively very good.
Browsing is a joy especially if you have opera installed
Pretty fast User Interface(Depends on current theme)
Included charger allows you to listen to music in headphones even while charging
Call list is very elaborate which sometimes comes in very handy.
Wi-fi is spectacular
Bluetooth is twice as fast as the N95 -8GB and supports multiple transfers simultaneously.
When a call or msg comes when ur listening to music it is not interrupted. You only get a beep.
Scratch proof screen although its a finger print magnet.
Business card scanner.
Never hangs or reboots.
Transferring files via the usb cable is extremely fast. You can fill up the entire 8GB in less than 15 mins in vista.
Watching youtube videos is really impressive with quick buffering times.
Cons.
No animated wallpapers( I miss that)
No .wbmp picture sms support( I miss that too)
Video recording is a joke
Cannot record voice calls
Creating playlists in the walkman player is a real pain in the a$. Miss the good old times when it was as simple as marking a folder and adding it to a playlist. Now you have to update music, wait for 5 mins, then browse the tracks and add each file individually. this is my biggest gripe in the phone.
Sorts messages only by server time which sometimes sends new messages way down the inbox.
No Edge and GPS and Airtel GPRS Sucks
Torch was absent but thanks to modders the G900s torch has been ported here hence no problems with that.
Sometimes when receiving large multiple files via bluetooth(abt 10-15 mb each) it gets slow as they are all first added to the messaging inbox and is hence constrained to the available phone memory.
T9 text input prediction is very wierd. its no good at learning new words and is not user friendly at all. I hate it.
No Profiles
No Video ringtones, accelerometer and shake sensor.
Just Go buy it folks. It wont disappoint you.
