I agree with Powder Extreme, and I have had 5 laptops. First, DO NOT buy a COMPAQ!!!!! They are junk and nothing but junk, out of 10 in the office they all died but one in 2 years and Compaq support is horrible. The batteries only charged on 3 of them right out of the box, and Compaq would not stand behind them. Toshiba is a good brand, I have owned one of them and it was a solid unit. Never had any trouble in over 2 years with it. I have had one Sager, they are nice units too. Great prices for the performance, but large and heavy. The only other down for the Sager is the software they come with, basically just an OS and that is it. If you have the software already you are set. I have had 2 Dells now and they are great, support has been OK but not great. Good prices too when you factor in the software bundles if you don't own it already. Gateway laptops have been solid from what I have seen, I know several people with them.
I would suggest a Dell or a Toshiba for a reliable economical laptop.
