|Just my opinion....if it has Vista on it don't buy it. If it will support xp or win 7 buy it.|
If it is a Vista machine...consider it to always be a Vista machine as there is a driver problem should you decide to go xp or 7.
You are going to see a lot of outlets unloading Vista computers and the reason is stated above.
I would look for monitor size.....hard drive size and memory. And is it set up for wireless.
Also take a close look at any warranty.....and does it come with any cds..(OS)
Laptops are becoming like Bic lighters....when out of gas you toss it. The repair cost can be more than a new one...........
