Query: WARNING: DO NOT USE WITH WINDOWS 7!

Kindle is not compatible with Windows 7. Windows 7 can not recognize Kindle as a hard drive, and thus you can not load books, documents, audio or pictures onto Kindle from your computer. I found this out after upgrading to Windows 7 from Vista (with which it does work); Kindle Technical support had NO REMEDY for this problem. If you have upgraded or plan to upgrade your PC, DO NOT BUY until the problem is resolved or until Amazon can provide a driver that will fix this problem.I love my Kindle, but right now, it's a $260 brick.
