What Does Mossberg Think of the MacBook Airs?

"Technology journalist Walt Mossberg has reviewed Apple's new MacBook Air notebooks, and has given both the 11-inch and 13-inch models high praise for offering the long battery life and instant-on capabilities found in the iPad."

The consensus among all the reviews I've seen is that this machine is very fast with the flash system it uses, and some have even said this can be a replacement for your primary computer. Walt Mossberg on the other hand, while he notes that unlike the past MacBook Air you can run seven or eight programs at once with the new ones, still thinks they are only replacements for light-duty users. What to buy, what to buy.
