Oh sweet! just doing some browsing on the net for a copy of Windows Vista (previously Longhorn) Beta 1 to download since I dont have an MSDN subscription 
. No luck on the download, but I did find an article on making an external display (like a feature proposed for Longhorn). I haven’t had a chance to read though everything but it looks very promissing, I’ll let everybody know how it goes.
I even have 2 PDA’s from work (one still works, just doesn’t have a battery) that I have been saving for this kind of a project! Oh perfect world!
