The back of the cover has a nice grip, but the shape tends to remind you that you are using a device. The lip of the clasp presents another edge when reading one-handed that bugged me. The front actually had something to stay put on the 650, and the T1 has nothing so the cover tends to flop a bit.
These are the things that bother me about the standard case too, especially the edge thing on the right-side of the reader. I would rather rest my thumb on the flat surface of the device than on a raised edge. A cover that won't stay put is also annoying. I wish it were more "book-like", similar to past Sony covers or the Kindle standard covers.
I bought the Sony cover because I wanted a lighted option for traveling. I am looking forward to seeing what designs become available from other vendors.
