I'm finally thinking about switching over to mac after a long wait (too long). I've been looking around their website, the refurbished section in particular. If anyone has had any experience with buying a refurbished mac (a mbp in particular), have you had any problems or issues with the product? I'm thinking of buying the 13" mbp listed at $1299, but my other option is to buy the low-end 13" mbp and upgrade the ram and hdd for a little bit cheaper. Thanks for your help.
