A friend of mine is a master real estate broker. He's a good example of someone can move almost entirely to a chromebook or an ipad because nearly everything is now web based. So it's not just old folks or people just surfing but regular people doing their jobs. In particular this guy is someone who has half his browser eaten up by toolbars and buys a new computer every few years "because the old one is too slow." A chromebook or ipad is a great place to park those people since they're curated environments and not the free-for-all virus delivery and identity theft machines PCs are for the unwary.
