Ok well sorry for the wait everyone finally back updating on this thread about what i think about the new SGS3.

Here is what i think SGS3
+ really fast compared to N900
+ really smooth compared to N900
+ camera is amaxing and quality is brilliant. Comes on instantly, no shutter lag, burst mode takes about 20 shots in one ago!
+ much more games and apps available
+ voice command is pretty cool but its not as quick and smooth as SIRI
+ the phone does lag now and again when lots of open apps and playing heavy games but its slightest glitch compared to lag.
+ to fully charge the phone takes about 5 hours
+ still phone only lasts with heavy use a day!
+ music player is pretty cool with equalizer
+ whatsapp etc available
+ browser isnt as good as N900 i prefer the full pc looking browser compared to mobile page browser! specially many web sites look and are so annoying!
+ has only got one wallpaper even though you have multi screens because of touch wiz 4
+ pretty good, smooth, fast UI.
+ face recognition unlock pretty awesome
+ some of the things i cant remember right now i'll update when i remember

If there is anything you would like to know then fire away and ask me and i'll try and reply back!

ciao
