It is an impressive piece of technology and software. Of course, as a long Mac user, I have some clues : GUI running on the 3D accelerator ; CoreAnimation for consistent effects and animations in the GUI ; an ARM11 running at 400MHz so higher than lot of smartphones (and which could run at 600). The result is impressive. It is a very good tradeoff. I have a data plan because wifi is not so widespread where I live. I was surprised to see that Edge is not a problem. I even compared with 3G on a phone from a well known company. The 3G phone was loading a mobile version of lemonde.fr and the iPhone was loading the normal version of the same page through Edge (using the same operator). Surprising result : the 3G phone was left in the dust ! It was so slow to load the page !! My conclusion : the physical layer is the bottleneck only when you use your phone as a modem, as a data pump. But, when the phone has to do the processing of the data (web browser ...) then the software stacks are the bottleneck. And that's why my iPhone with Edge was much faster to load the page. So, the lack of 3G is really not a problem. The only problem I had is for synchro with my very old Mac because my very very old Mac has only USB1.1 and the iPhone is supporting only USB2.0. So, it is working but no so well : it is slow and sometimes, the connection between the Mac and the iPhone is broken and I have to restart iTunes. But, except this problem, I am in love with my iPhone too. Other phones look pathetic compared to it. Of course, they have better hardware but who cares ! The real difficulty does not consist in putting as much hardware as possible. The real difficulty is in making the right tradeoff. It is often more difficult to remove a feature than add one. Of course, the iPhone is not perfect and that's why there will be lots of software updates and version 2 of the hardware. But for a version 1.0 it is as perfect as possible. An impressive device !
