Perhaps it just is that nobody has found the porting or developing business apps attractive enough, or then it is just the Nokia E-series business phones that gets all the attention and effort.

I feel that the N8X0 and Maemo platform have the true potential to develop from IT-hobbyists toy to a business tool, but it does need decent software support. I would be interested to commercialize such products if there is interest from the skilled coders (such developers please contact, if interested!)
