Hi there - I'm in Canada and was thinking about ordering an MBA 13"/8gb ram/128gb SSD for $1200 online, but then the baseline model with 4gb went on sale for $950 today at Future Shop and Best Buy. Is the 8gb upgrade really worth an extra $250 (26%) cost, or does the 4gb base model perform well enough? I've got a young family and money is sometimes tight, so I'd like to save the money if possible, but I don't want something that will be performing poorly in a year or two. I would be using it mostly for Office, web browsing, Netflix, etc, but I also sometimes dabble in Garageband and light editing of photos and home video. FYR, I'd be upgrading from a 2007 Macbook (3gb ram/128gb HD) that is starting to get a bit flaky lately. Thanks!
