@DeathByVisualStudio: I have a 4.5" 920 and it's a bit large (for me) as a phone. On the other hand, the screen is too small for browsing the web or watching a video, for that I need 10" or more, due to my old eyes Smiley

So, while the "convergence device" idea has some merits, I subscribe more to the star-trekkian concept of almost disposable, single purpose, low cost devices, each tuned to their specific usage scenarios.
