I had some unexpected problems with my old macbook come up over spring break so I replaced it with a new rmbp with the 8 gigs of ram and 512 hard drive. I had issues with programs crashing unexpectedly so I exchanged it for a new one. The laptop keeps randomly freezing even though I'm no where near using my full ram or cpu. I'm trying to decide if I should exchange it for another one, return it and get a pc, or try to make it through the last 3 weeks of the semester with my ipad and wait to see what comes out in June.
