My mother's laptop (a Toshiba) just got drenched in a glass of red wine so I thought I'd get her something new for Christmas. I've looked at a couple of HP laptops for her but I'm also considering getting her a 13" MBA. She's quite frugal and has always bought low budget laptops that are SLOW (which end up driving her crazy). I'd quite like her to have something a bit more snappy and I think she might also find a mac more user friendly. She mostly uses her laptop for emails, word processing, viewing and sorting (but not editing) photos, and web browsing. Would 4GB last her for a while? She's not the sort of person who upgrades regularly, she uses what she has until it doesn't work anymore, so I want this to be a long term investment.
