As you can tell, I was very happy with the Keeper 360 case by Fortte for my Xyboard 10.1". Sadly, that honeymoon phase is now over and I wish I hadn't purchased this case as it wasn't cheap by any means. My main complaint is that I chose this case over the Incipio case because of the magnetic closure. I had the Keeper case for my XOOM and it had a strap with a magnetic button to keep the case securely closed. Instead of that strap, Fortte used a magnet within the cover to hold it shut. In theory, this should work just as well and as far as it's strength, it works without the tablet in the case. However, once I insert the tablet, there is absolutely no way this magnet is strong enough to keep the case closed. Disappointing to say the least and due to this annoyance, I'm ready to go the Incipio route. I'm going to contact Fortte regarding this issue and see if there is any solution to my problem, but in all honesty, I think I'm stuck going the Incipio route.
UPDATE 4/13/12: I sent an e-mail regarding my complaints to Fortte because I wasn't happy with the 360 Keeper case. I was assured that the mechanism for the 360 is the reason some design changes had to be made from the original Keeper case and as such sacrifices must be made. However, that's the bad news and in all honesty, Fortte is an excellent company and has provided me with excellent news! Peter, a representative at Fortte, has offered to custom make me a XYBOARD Keeper case based off the original design. This should clear up my issues with the case and be just like the case I had for my XOOM. My suggestion to everyone who decides to get a case, and if the 360 turning isn't a big issue to you, request a custom made case. I believe it's possible based on what I've been told by Peter.
Once again, Fortte has done right by me as far as I can tell. I will report back once I receive the case, but he assured me that it will be just like the original Keeper so I'm extremely excited!
