Microsoft Touch Mouse vs Arc Touch Mouse vs Wedge Touch Mouse

Which one would you recommend for my brandnew W8 laptop, basing on your own experience?

Touch Mouse can be used with gestures, which are always a big plus for W8 (especially when screen is non-touch).

Arc is... hmm... portable, turned off takes a little of the space (perfect for laptop bag).

Wedge is the small one. And I wouldn't even consider it, if it didn't have Android support, so it could be used with my Galaxy Tab.

So, again, which one would you select?
