All the limitations of the iphone, including no real keyboard, no multitasking, lack of I/O connectivity, etc., with none of the mobility. The iphone works because it does things efficiently and neatly in a small phone you can put in your pocket. But with the iPad(I can't believe they chose this name. Queue the feminine hygiene jokes LOL!), it's the size of a small laptop, but has none of the flexibility of the laptop. I predict this thing will flop big time. Just my $.02.
