I know what you mean about those novelty systems.  I don't want the Turbo systems going in that direction. 
 It would be cool if NEC restarted in the hardware industry by making a portable system that is all new that plays huCards for backwards compatability and its new native format.  OF course the handheld market is dominated by Nintendo, which is a partner with NEC and Hudson in certain fields.   The rumoured Microsoft portable gaming system is a nice idea, but I want a portable gaming system and not a portable media system that plays games next to a hundred other things.
