It is worth to make game for windows 8 tablets?

Hi guys,

I already did some decent game and publish it on google Play. Now I am Developing a new much better game and I was wondering if is it WORTH to publish it on Windows Store(ofc also on other stores).

I dont have any W8 tablet so I got to buy one. I have so Questions about W8 tablets?

Can u it run Unity?
Can u actuelly develop on that(with mouse and keyboard attached)?
What u think about Windows Marketing?
When I have playable game for Andriod will be it easy to convert it on Windows?
