iPhone mk2
I think many of us will wait for the second generation iPhone.
I've seen the 25 minute video on the iPhone and the interface and usability is a breath of fresh air. So many phones have appalling interfaces. It's like designers are stuck in the 1990s still. But the iPhone interface is so easy to use, anyone will be able to use it.
It's just a shame the first iPhone will cost so much to offer so little. When you factor in the expensive contract (24 month contract?), lack of removable battery and sim card, it makes you wonder what planet Apple are on.
It makes me wonder if they were asked to make the SIM non-removable so you are locked into some expensive contract for the life of the unit.
The speed of the internet will be crucial for those after a mobile net device. TCP/IP doesn't really work too well over phone networks. There's a lot of potential optimisations that can be done to make even an EDGE connection work fast.
