This has probably been addressed many times in the past but I'm ready to buy and there are many more models on the market now, so I need your help. I was really eying the ClamCase Pro but reading some online user reports it has a tendency to crack after moderate use. Solid connection and a keyboard with a great typing experience are of course primary considerations. I'm not tied to a price so that's not a real factor. Let me know what you think. Thanks.
