First off, you should have posted this in the iPhone Accessory subforum.

Second, I've actually used this product before. It's nice and works fairly well, but the drawback is it becomes your case, plus it can be buggy and make your phone kind of slow.
 
well I bought one thinking It was going to be awsome, this just ruins the bulk of the phone. it runs out of charge in a couple of hours. I would not get this, the idea is cool but when you have it, its not.
 
i like one of Cath kidston flip leather iPhone 4 case, and i bought one last sunday. really beautiful!:)
 
this thing has had terrible reviews (the keyboard for the iphone). i've seen it from $40-70 on amazon, and literally every time i look/ask someone their opinion about it I hear terrible things.
