I just want to throw my two cents in about how important Mobile support is for this product.
It’s not the future - it’s now.
I don’t expect this product to natively support mobile device features, but I would hope there is at least support in the form of code generated that works well on Mobile devices. This means at a minimum - the layout resizing, the controls resizing, and gestures working.
In the very near future, a large percentage of people browsing today at a PC will be browsing on a tablet.
