Dunno where you get the idea that Windows machines suck. They use the same hardware as Macs. High end PC's stack up well against Apple's offerings. As is many times the case, you get what you pay for. You can't expect a $200 windows laptop to compare favorably against a $1000 MBA.
I stand corrected. Their hardware is inconsistent and generally bad, and their software/hardware integration is non-existant.
