iPad and the Smart Cover

OK, iPad readers. What do you think of the Smart Cover? Any suggestions?

I was optimistic about the iPad 2’s Smart Cover and got the red leather one with my iPad 2 on launch day.

It mostly works as described, but I’ve been disappointed in a few areas….

I knew going into it that the back of the iPad 2 would be unprotected by the Smart Cover. In practice, I find that I’m overly paranoid about it getting scratched by grit on flat surfaces, such as a grain of sand on a table, so I don’t feel comfortable setting it down on most such surfaces. …
The bigger issue, though, is the practicality of actually using the iPad with the Smart Cover.

The auto-unlock is nice, and I love the minimal bulk, but it seems like it wasn’t designed to stay attached while you’re holding the iPad, because there’s no great way to hold it.
