Re: What top 5 features/benefit would you like from BB10 on the PB?
1. More stable, performant and better laid out browser
2. Hub (much faster/more convenient than launching messages)
3. New gestures (especially the swipe-up which I was never very fond of because it felt like a button press)
4. Docs to Go (better design/layout, new features)
5. File manager (native zip/unzip, tight Box/Dropbox integration
All of these, imo, would send the intrinsic value of the PlayBook through the roof making it much more appealing with or without apps.
p.s. I'm including the keyboard under gestures as they're what make it so special.
