Your comment is nothing but a sneaky way to insert anti abortion propaganda into this conversation.
No thunderbolt, no firewire, no USB 3.0 listed.
No multi touch track pad, no back lit keyboard.
720p camera, asus only says
Magsafe power adapter, longer battery life
Also the mac runs windows, linux, AND OS X. The asus does not run OS X (without LOTS of effort to install and maintain)
The mb pro looks much much nicer.
All in all, quite a few differences. Add in all that stuff you missed, and you're nowhere near $749. The only two things it exceeds is hard drive size, and video card. You can get different set ups on the mb pro, but there is not point in discussing the asus any longer since it is no where near the specs of the mb pro you listed.
