Ubuntu works perfectly for me. I run all sorts of applications that you can
imagine of. I have a telescope and use KStars to stargaze and parallely run
ktechlab for some digital circuit simulation and with so many browser
windows opened at the same time. I have had no problems what so ever. I have
even tried to load both cores to over 80% and use over 80% of memory and
swap, and it has worked for me. no freezeups.
