Markoff's may well be right. The time seems ripe for the debut of a simple, cheap, lightweight portable with a browser, a wi-fi card, and nothing else. (OK, maybe a little flash drive, too.) If you really want to jumpstart the adoption of online productivity apps by business folks - and make Microsoft very nervous - create a cool CloudBook for road warriors. With the iPhone, Apple is demonstrating that the Web itself can be a platform for writing and running software. Why not take the next step?
