I think the price difference is not a small point. The Apple store has the 11" MacBook Air starting at $999. My netbook was around $280 and is a device that does exactly what I need.
The $719 difference is no small change for me either. But it's still easy to buy a well-supported 11" laptop. Truly replaced form factors have it even harder. Try to find a "dumbphone" that was designed with enthusiasm.
