Summary: Hard drive comes partitioned OS and Data, no big deal, but I had to spend the time to extend and make it a single partition. Battery life seems ok, 4 hours if you're nice to it. Max supported RAM is only 8GB, mine came with a single 4GB stick and the other slot was free.
Pros: Very fast, compact, decent build quality. One of the fastest for its size.
Cons: Rubber feet will fall off if you're not careful with it. One fell off, so I took them all off and just super glued them on. There are screws under the feet also. 4GB ram, the first thing I did was max it out to 8GB, well worth doing. Lots of Asus crumware to delete.
