I love how you say that you can play all these games 'flawlessly' and it runs 'so fast and smooth'. You fail to mention the resolution and the graphical settings. I've played skyrim on my 13" Air, and while it is PLAYABLE, i would certainly not say 'so fast and smooth'. I believe my settings were on medium and native resolution.
For skyrim I am using a couple performance optimizers and it runs VERY SMOOTH and Clean.....at 11" 1280x720 looks GREAT....and I have texture set to high and everything else set to medium....the pixel density on the screen makes AA not needed. I will take a video and post it so you can see I'm not making it up.
Go ahead and do some research on optimizing Skyrim before making comments like that. Have you seen Rage running??? Its pretty incredible!
