I'm still a windows 7 user, but if I were to switch to windows 8 I would definitly be using start8.
I noticed something in your start8 demonstration video. when you moved the cursor down in the lower left corner, the metro pop up button appeared so that you had to move the cursor away, and then back and stop over the start button. very often when I'm using the start button, I quickly drag the cursor all the way down in the lower left corner and click, but if I were to do that in w8 with start8 the metro pop-up button would be in the way. so my question is would it be possible to get rid of the metro pop-up button?
