As much as I have loved my 13 inch i7 MBPr in most ways, I do have a reservation: in the 9 days since I bought it, it has crashed twice. Both crashes happened while I had VMware Fusion running and Windows 7 loaded in the virtual machine, so they could be the culprit. Even so, I wish stuff like that wouldn't happen. My old 2010 13 inch MBA would run for weeks or even months at a time with nary a crash.
