1. Led flash is very useful, but xenon flash is better. But cannot compare to a normal compact camera for quality. To me, phone camera is useful for quick snapshots, qr code, goggles, augmented reality.
2. Good, can get better quality for video conferencing. Though not critical.
3. With optimized kernel, 512ram seems enough. Linux is famed for its low hardware requirement because it is very efficient. (unlike crappy windows). My netbook running on fully functional arch linux only consumes 57MB ram. I will be disappointed if future android requires more ram to run. However, 1GB ram is very useful for gaming.
5.i believe so. The atrix will only have 1080p recording after a firmware update.
6. Dual core = less battery consumption. Coupled together with higher battery capacity, will give longer battery life. Really nice.
Don't forget about near field communication too.
to me, battery life and faster processor is what I'd like. The rest are gimmicks especially I don't do those casual gaming on a phone.
While dual core speed bump on a phone is nice, it will give much more impact on a tablet. I wanted to see a miniature desktop core2duo performance on a tablet where I can run not only android, but conventional linux like ubuntu as well. I imagine running lampp server, play football manager, civilization, etc on a tablet

if I can run those on a phone, that'd be superb!
sgs is fine for my needs. Sgs2 is better in every way but it doesn't do enough to justify for an upgrade. YMMV.
for those thinking of buying a smartphone for the first time, you won't regret buying those dual core ones like sgs2.
1. LED flash is better than no flash. least you get usable (means its not high quality but you can see who it is) night shots. SGS? can't take any shots in the dark. fact. and SGS siblings FASCINATE & EPIC has LED flash, i fail to see Samsung's failure to include it in SGS.. yes I am rather sore over this
2. no comment.
3. more ram is always better. remember the famous fail statement that Bill denies?
yeah, don't be another Bill Gates. RAM is never enough.
5. ditto.
6. ditto.
