I think the problem is people are expecting all the functionality of the iPad, this is simply a e-reader on a little bit of steroids. For me the device has been good, the issue with the .mobi files confused me also but really they just appear in the Doc section. If you go to this expecting for an iPad, you will hate it. If you want a simple e reader that lets you browse the web and download some apps, then its great.
