I found the 6610i keypad a bit weird as well- I actually preferred the 7250i!
Hmm... I feel like I'm a sucker for mobile phones... whenever a new one comes out which I like... I just have to get it... atm I'm currently using a D600, but my past 6 or 7 phones in the last few years have all been Nokias- 8310, 3650, 6100, 6610i, 7250i, 9210, 7610... am also using a w800i (because my Dad can't stand it) but I also find it damn hard to use... It's got really nice features and so on, but when the interface comes into play, it just annoys me because I'm used to Nokia?
As for the other nokias mentioned in this topic.. n90 is nice but yes it's definitely too big- it feels awkward to open with one hand... and the only use of the swivel lens as seen in the add (where the guy rotates it to follow his son jumping on a trampoline) is pretty much the only use for it... but doesn't justify the extra weight/shape and lack of vibration. the n70 is very nice, but i feel like i'm about to drop it everytime i hold it... the weight dimensions are funny, but i like the modified s60 interface. What I don't get is why Nokia changed the power plug for their new nokias...
