The AcerAspire S3 is an ultrabook. Basically, they look like macbooks but depending on the price you pay determines how it feels and specs of course. Anything less than $1000 will probably feel cheap. I found an ultrabook with almost all of your specs other than the cpu power and 1tb hd, but you won't find high specs in ultrabooks due to lack of space (unless you go into the $1000s range). They are still very cool though.

Up to 8 hour battery life and a decent gpu in an ultrabook? Sounds good to me.
One thing I could gripe about the ultrabook is that the max resolution is not 720p hd. It is 1366 x 768.
