Linus made the right engineering choice when he took the monolithic route in the 90's. However, the technical advantages of that architecture are now moot. Sooner-or-later, Google is going to get tired of Linux's shortcomings and build a replacement OS.

Good luck getting the drivers working for all the esoteric USB/Bluetooth devices in the wild. IMO, Linux's greatest advantage is not it's technical architecture, but the breadth and depth of people and organizations working on it.
