I've got one Toshiba here, soon to be 12 years old and the other one is about 6 years old. The old one is in a drawer, but everything works like out of the box. The only thing is XP is slow on it, it was a Windows ME computer, it's only 660 mhz. I bought both at Staples and they have always worked, never needed warrantee work.
At the office and at my brother's house, they had Acers from Radio Shack, nothing but pieces of junk. They would just go black and seize, not even 6 months old.
