Asus makes cheap laptops. No doubt about it. Their netbooks run around $300 and you normally get more for the price than you would in an HP or a Dell netbook of comparable price. The only reason they don't get a 5 star here is because Acer has recently dropped their price to be slightly lower than the comparable Asus netbook.
If you are not into the small, weak netbooks they have a line of much more expensive laptops that have done really well on the market. These laptops range in price from $1000-$2000 and pack in some of the best hardware out there. We'll get to the value of those prices in a moment, but for now we'll say they are comparable to the prices of your average Dell, Sony, or HP.
What I like is that, if you are interested in something in between, Asus has a laptop that is the same size as their netbook (10.1 in) but packs in some better hardware without jacking up the price insanely like many laptop makers will. This laptop, the N10 series, runs around $700 and packs just enough hardware inside to run Vista and your normal applications. I like that Asus offers this option when many other companies do not.
