Fujitsu laptops have been brilliant for me, up there as one of my longest lasting laptops, I'm hard on them and current one is over 2 years old (October 5th 2012). Previous laptops have lasted a year HP, Toshiba 2 laptops: 1.5 and 2 years, Dell 2 laptops 2 years (1 whilst having a desktop). IBM currently still top with 4 years, but at the time I had a desktop too so it only got half the use and had to replace the mouse.
So overall the Fujitsu is probably he winner for amount of use and length of time. Was also a good price! Early Dell laptop was around $4,000 my Fujitsu was around $800.
