Actual use?

I still can't see a point to the iPad. The touchscreen looks nice, and as someone pointed out the powerpoint clone looks actually useful, but the big iPhone without a phone just seems kinda pointless. Maybe useful for graphic designers? Maybe useful for salesmen? Although a proper tablet pc would be better. Any other ideas, or is it just for people who like new shiny toys?
