8 Gb MacBook Pro memory upgrade
Just upgraded my MacBook Pro to 8 Gb of RAM. Cost is about $35, and time investment about 15 minutes. Pretty easy, and so far so good. Everything feels a little snappier and more responsive, I launched PhotoShop, Skype, Spotify, iPhoto, Chrome and TeamViewer all at the same time, and the amount of memory free was still around 5 Gb
