Just got this phone yesterday, not very impressive -.-
Get hangs and lag pretty badly frequently that I have to switch off and on the phone..
The touch screen isn't too smooth (Well compare to iphone and such)
Annoying loud clapping sound when pushing up the screen for the keyboard.
Backlitting for the keyboard is stupid as well. Could be the light sensor isn't sensitive enough, it lits up even though its exposed under the bright room light, and making me even harder to see the words on the keyboards.
Without the backlitting, every words is black and it's so easy to see rather than backlitted.
Though, in the dark, the backlitting is very nice.

And the SDHC micro SD memory slot is just stupid, you have to remove the back plate for access and what even more stupid is, it is very hard to remove the memory card once you put it in place (I'm not sure if this is my phone problem or not though)

And another thing that I noticed is the music player, it's even worst than N95, in terms of interface, there is some improvement, but for music quality, it's downright lousy.
(Well, I've got my proper portable music player so this isn't a big deal for me anymore)

Hope the future firmware will fix these issues.

77mb for the phone memory is just bad...(Even lesser than N95 which have around 140mb+)
I get a lot of "Phone memory low" warning messages quite frequently too..

32Gb Onboard is sweet though. But that's about it, I'm not sure how am I gonna fill them up lol.
The web browser..I wouldn't say it's great but yes it's now usable comparing to N95's one (LoL)

Anyhow, the large sized screen is nice, bright and sharp (Too bad touch screen isn't good/responsive enough)

I should consider selling it..soon perhaps.
