It's been said to death various places on the internet, but the lack of inputs, and the lack of a easily replaceable battery (it's "integrated") are a huge loss. It may be wireless and have few wires to deal with, but you'll have to deal with USB hubs and other cables when it's in "desktop" mode. Traveling usage (for anyone other than those who carry spare batteries) will probably be OK though slightly inconvienenced. I wonder if Apple will come out with a USB "dock" for desktop mode.
