Just want to note that, when I talk down about the majority of 768p panels, it's not because of the resolution, but because of the poor technical specs: contrast ratios are in the 200:1 to 300:1 range, viewing angles are very narrow, colors washed out, etc.
But those may not be huge factors to everyone. It's not like they're unusable. I preach the gospel while daily linking numerous people to budget laptops which contain the very screens I condemn.
I'm a person who spent $200 on a premium screen upgrade, for my current notebook, because I want the LCD I stare at all day to be pretty and I've had enough experience with screens which you have to adjust every time you move you head to know it's aggravating.
Also, on the ~$800-$900 vs $500 laptop decision, and I should always mention this. There is something to be said for luxury. A machine from the VAIO or Samsung crowd should certainly feel better than the average $500 Acer/Toshiba/HP. But that's why it's best to read some user and professional reviews, instead of buying based solely on spec sheets. Factors like what kind of feedback the keyboard gives when typed on and how sturdy a machine is in the hand can be worth hundreds, to some. But
