There are already a lot more mobile phones on the planet than there are PCs, and mobile phone sales are growing rapidly while PC sales seem to be faltering. Global sales of new mobile phones topped a half billion last year. Increasingly, those phones are doing things that people used to do primarily on a PC (smart phones are 5% of the cellphone market and doubling each year). But how far can this process go? Far enough that some people won't bother with a PC in the future? Handheld computers used to be accessories to PCs, but as they become connected to high-speed wireless voice and data networks, some businesses have stopped deploying laptops and are instead deploying smart phones to their employees. In Asia and to a lesser extent in Europe this seems to have happened quite a bit at the consumer level, too. Newsweek is sitting up and taking notice (includes some nice quotes by Jeff Hawkins, ever the visionary): http://msnbc.msn.com/id/5092826/site/newsweek/ It's hard to know how all this will shake out for individual OS platforms like Palm, Windows, Symbian, Blackberry, etc. but it's not hard to see that there are opportunities to be seized.
