Trying to buy a laptop V2.0

Hi again guys, I've had some new developments in trying to buy a laptop. Originally I had a budget of up to $400 for a laptop, however I've recently gotten some extra money so I've been able to raise my budget roof to up to $700-$800 area.

As Maziar suggested, I've been considering the Inspiron 11z and IdeaPad which was dicussed in my previous topic how with my increased budget I've been trying to find new options.

Originally I was very set on trying to get a netbook for the weight, however I've noticed more and more, ultrathin laptops with a weight equal to netbooks but with much higher performance.

What I was wondering is, with my price range, what would be the best bang fo rmy buck? Should I consider a high end netbook, or is there a nice ultrathin (around 3 pounds~ish?) which could meet my budget, or close to it?

Thank you for any help, I really want to put a lot of thought into this, the bulky-ness of the laptop isn't what matters, it's the weight, so if I could get a lot more screen size but at the same weight I'd be very interested.

Thanks again for all the help.
