I just installed Windows 8 Consumer Preview (beta) on an old Dell D830 Laptop I had lying around. I installed the Win8 Metro Testbed (from Splashtop) on my iPad, installed the streamer app in Windows 8 and viola, I have Windows 8 with full gesture support on my iPad. I then found a WordPress app to install from the Windows Marketplace and here I am, blogging on Windows 8 from my iPad.
I just love technology. Such fun! ☺
