I have 2 Toshiba and an Acer. No problems with any, touch wood.
Oh, that's not quite true. The Acer was just over 2 years old when the CPU went. Thankfully, I had purchased an Extended Warranty. The CPU was replaced - took 3 months - and no probs since.
Toshiba's were only purchased last year, so don't expect any trouble until next year.
Am going with a Toshiba or ASUS Netbook when the new models are relased, next month.
A computer chap says laptops are only built to last 2 years and that by that time techies consider them old.
