I have to say it blows away the N800 in terms of usability, accessability and UI responsiveness. All applications worked and worked the same way, the gestures to perform actions such as deleting an email are intuitive and apps respond immediately - no pauses while the touchscreen fails to register or think about an event, no lag when displaying photos or videos (photo AND video scaling is impressive, the N800 even with mplayer is sadly put to shame [I blame the cruddy video bandwidth and lack of hardware acceleration]), and applications when started appear instantly. I then pulled out my N800 and started Kagu, which inexplicably crashed (it locked up on the main scroll screen and I had to kill it, and now it's not starting at all). At this point it occurred to me that maybe Apple has a point when they try to restrict what software is installed on their devices! I also noticed how long it took apps - any app - to start on the N800 as apps start almost immediately on the iPhone whereas on the N800 the infoprint appears for several seconds before the application appears (how have Apple achieved this?) Then started the comments about my "steam driven technology" so I put it away having taken a severe verbal beating! Everyone was impressed by the iPhone - even other restaurant diners were craning their necks for a look - while the big, fat, ugly N800 was derided.
