As an Iphone user, I would have to agree with kickstart on the battery life issue - my Iphone 3G can only run in standby for like about 36-48hrs absolute max before it needs a top-up. Just for comparison, my old (circa 2001) nokia 6210 gave me at least double that (or probably more) consistently for about eight years. Apparently the newer 'S' version is about 25% better in this regard..
The only other negative thing I have also noticed with my iphone - occasionally (on the order of once per week), it throws the odd' wobbly i.e. application crash or phone crashes when one attempts to make a call.
Comparing this with my old Nokia, I cannot even recall ONE event where an application hung (even on WAP browsing, which was a good exercise in frustration..).
Of course, all the above may be due to (alot) more stuff going on 'under the hood' (in the case of the iphone
) I will see if a firmware update (from v2.2.1 to v3) will help
