What you’re saying makes absolutely no sense. Don’t use your finger to move the cursor on your MBA on a MUCH SMALLER pad than the screen? And BTW, all Windows tablets have USB ports (unlike iPads), so if you want to use a mouse, you can do that too.
[I’m not saying that a regular Windows 8 is useless.
I think that’s precisely what you’re hinting. If OSX tablets were available, you’d probably consider them the best thing since sliced bread.
