Upgrading RAM in the MBP
I'm about to buy a MBP with 512 MB but I'm thinking about upgrading it up to 1G or 2G depending on the price.
My questions is:
Should I upgrade it at Apple? Or should I buy it from a third party store (which is cheaper right?) In this case, which brand is more reliable? Will this cause those "unexpected shutdowns" ?
Thanks for your help in advance.
