I'm pretty sure this will appeal to a *modest* number of you - there's now a "developer preview" release of the Windows SideShow technology that runs on Windows Mobile devices. SideShow, if you remember from the Vista release, lets you "stream" PC updates and information to an auxiliary remote device. Now that apparently can include WM devices! The Unwired has some very, very interesting screenshots showing Windows Mail (not Outlook, but Vista's built-in mail app) sending updates to the homescreen of a WM Standard device. Cool!
Check it out at the Unwired, or go straight to the MS download page.
