Been running a Toshiba Satellite lappy for five years now. Works very well. Only hiccup was the hard drive which went wonky after 4.5 years. Managed to clone it and install new HD with Win 7 for $230.00. Now runs like new again. The hard drives always seem to be the weak link on putters (mine anyway). If everything else on it keeps working properly, will consider another HD replacement in 4 years just for the hell of it.
