V6 Mobile didn't carry lots of personal properties, so you could get away bysharing forms between Desktop & Mobile.
V7 Mobile on the other hand has got it's own properties to take advantage of. After a series of testing and prototyping, I'd like to share a simple but valuable experience.
You will get the best value by providing each platform it's own form and query. Label positioning, Width & Height setting, using sections and separators should be designed for each specif platform.
Note: Aware does a fantastic job rendering a Desktop form on Mobile or vice versa, but since the Mobile has all the desktop features, you get a much better result by customizing each one separately.
My two cents!
