I feel like I have a new computer. EVERYTHING runs faster. This Macbook has been my sidekick now for 5 years I think. It has lasted unbelievably well with no real issues and one optional software upgrade. If you haven't already, do yourself a favor and buy yourself a Mac computer. Unless of course you're a mac hater, in which case you can't read my blog anymore.
But seriously, buy one. You'll love it.
