The best hope for PlayBook and for RIM are quality tools. We need a better document writer, we need a far better PowerPoint slide tool, we need loads better music composition tools, drafting tools. Why not take a look at the most highly rated apple stuff and find an opening to perform a similar function on PlayBook?
Help people, don't play them for rubes. There's real money to be made and glory to be had, with little to no negative feedback, for developers who embrace the potential of this tool and show RIM how application development is done.
Survey the field and go for it. Aim high. Quality is King.
