His complaints:

(1) You don't know how it will _feel_ (It's Apple so that's pretty much the one thing that is guaranteed to be fine)

(2) You don't know which iPhone apps will run correctly (get over it, the software will be buggy and under-featured for the first 6 months, but the web browser will work great and that's all that really matters. Remember iPhone OS 1.0?)

(3) How much will iPad-only apps cost? (A good question. My guess: another race to the bottom)
