My mom wants to pick up a new laptop to replace her ailing Sony VAIO one. We were going through Costco and saw a few in the three to four hundred range but I was hesitant due to the brands. If the guts are the same, is one brand better than the other or is there no difference? She's a pretty casual user, checking her email and running a few life insurance programs for her job. That's about it though, no games or anything. Thanks all!
