Way to go!
Start8 is just what Windows 8 is missing for the desktop UX. Kudos to you guys! I love Windows 8 because of all of its improvements, but I hated having to memorize a bunch of WindowsKey+SomeOtherKey in order to remain as productive as I was with previous versions of Windows.
This is a game changer for me. Perfect. The way Microsoft should have done it for the desktop user.
If you can afford it, you should spend some money marketing this to the masses of people who will soon receive new PCs with Windows 8.
Regards!
