You can find some pretty neat handmade covers on sites like Etsy. I got this one:
I was actually surprised by how well made it is. It's padded so offers good protection, although of course not pressure protection like a hard cover, but then I wouldn't put it somewhere that it could get that kind of pressure. Always screen side against something rigid or the back of my backpack (where it's against my back).
That kind of cover is also one of the least cumbersome, I don't think I could put up with some of the bulkier covers...
