With $25, an iPad and a bit of curiosity, you can try Windows 8 on a tablet right now.
Splashtop, a maker of remote desktop software, has released a $25 iPad app called Win8 Metro Testbed. If you’ve got Windows 8 Consumer Preview running on a PC, Splashtop’s app will stream it to your iPad, while allowing for all the same touch gestures you’d get on a proper Windows 8 tablet. For example, you can switch apps by swiping from the left side of the screen or bring up a list of options–the “Charms” bar, as Microsoft calls it–by swiping from the right.
