If there's a better place to post this, please let me know ...

I'm wondering if anyone knows, has seen, heard, etc. of a PDA (ie: device that is not a phone) that runs Windows Mobile OS and has a slide out keyboard like the HTC phones? The only thing that's even remotely close to what I'm looking for is the Nokia N810 internet tablet, however, it doesn't run Windows Mobile and there's one app I absolutely need (iSilo) that won't run on it.

Thanks,
Harry
