I originally ordered a cheap TPU case from HHI and figured I'd leave it at that for a month or two, but after seeing some Smart Covers at Microcenter I decided to pick one up on impulse. Today I went ahead and removed an outline for the Smart Cover (about 90%) from the left side of the TPU and it actually has worked pretty good so far. The TPU case has stayed on, and the Smart Cover works just like normal. This should definitely hold me over until the Feather or another case comes out that supports the Smart Covers. I'd recommend giving it a shot, especially if you purchased one of the cheapy TPU cases. I just used regular scissors, btw.
