What I like from BB9700:
1. Screen. Clear and fine, simply superb.
2. Optical pad miles ahead from nokia. Sensitive and easy to use. It should be the industry gold std.
3. Ergonomic, slightly thicker but lighter than E72, easier at the hand and not easy to slip off.
4. Software is rock solid and secure.
5. Looong battery life so far.
6. Browser speed is surprisingly good and has improved. Now is a joy to use. It renders flash page better than E72
7. Camera software is better then e72 but e72 quality is better

What I dislike from BB9700 are:
nothing so far

What I like from E72
1. GPS map installed from mem card
2. A wealth of S60 applications available
3. Nice keyboard
4. Flashlight
5. Ability to remote lock the phone via sms. BB should make this as a std too.
What I dislike from E72
1. Often hang and need reboot,
2. Camera hard to focus >_>
3. Optical pad sucks compare to BB
4. Slim but heavy. Not so good ergonomic, easy to slip off.
my feedback almost like below

edit from other internet site
well u got ur own point there...
i thinks nokia made it a little bit heavy, because u will feel its 'solidity' when u hold it with ur hand..
and also e72 is cheaper than bb...
