engineers.
marc andreessen did a talk a few months ago at Stanford (get it at ecorner.stanford.edu) where he talks about how the mobile app market looks a lot like the early days of boxed software - a million half-decent attempts but nothing really amazing.
and then came microsoft.
the world of mobile apps seems at present to be an arms race and most of that $20m is likely going to be spent on the guns and bombs of the tech world: great engineers.
