Actually, the US store has been out of N900s for some time. Dell's stock has also been gone for 3 or 4 weeks, and they've been selling N900s for about a year.

I got mine used on Amazon =D! Only 330USD!

PR1.3 is out there, and it should be released soon. As far as I've gathered, we get flash 10.1, Qt, and minor bug fixes.
