I bought the 2011 1.6 i5 4gb ram 128gb of storage. I am very impressed by how snappy this machine is. The whole package is superb. What i like most is the thin palm rest, you dont get that edge digging into your wrist. I chose to buy the refurbished model no complaints there. Same with the wifes new ipad. One question though how do i restore the machine. Does it have a recovery partition?
