I also have a poetic hardback. Good case, sturdy and cheap. The top cover clasp doesn't really work for shit though. Also, can't use the camera with the cover folded back.
edit: I found said case on amazon. Like I said, nice and cheap. Not a bad option.
Well, thanks to your suggestion, I bought the poetic case that does not include a keyboard (for $15).
I've already got a keyboard I like a lot, but the case is something that's been needed for a while if I plan to take the device out of the apartment.. (which I do tomorrow, for work (I'll be on site at a client's location and I'll have to keep track of information in a spreadsheet. No extra laptops around the office for me to take and I don't have a company laptop (yet?)) Too bad my case will arrive on Friday =P)
I'm glad to hear a good review of a similar Poetic case. I feel comfortable buying their other one thanks to your review here and similar reviews on Amazon of the one I just purchased.
