No multitasking ... at all.
No flash.
No USB.
No proper OS (iphone 3.2)
No built in stand.
No keyboard.
Not small enought to carry every day.
Not powerful enough to take on holiday.
No 3G on cheaper models.
No thanks.
Its a tablet they do not have keyboards. And your wrong here though. You can get a dock and it works with any apple keyboard and has the on screen touch keyboard pop up when you need it.
Stand - Daft to see these on these things, they do not need it built in.
No 3G on cheaper models is not a thing to moan about
Not small enough to carry? The cases at least for it like folders are very nice and certainly something you can carry around very easily.
All the other stuff and other issues are dam right about but those bits are wrong to gripe about.
