So what's happening to the PC industry? It's moving from the old world, in which one buys a PC and cares a great deal about its comparitive hardware features (does it have a DVD player?), to one in which the hardware is nearly identical, and the value's moved to services available through the device. Over the network. Battery life matters more than processor speed. Size of display more than disk. Access to Yahoo! Personals matters more than all of the above.
While I'm not sure about the rest of his post, this particular point is an extremely important one. Unless you are seriously into computer gaming, the hardware simply does not matter any more. Can I plug my digital camera into it and upload photos to Flickr? Wonderful.
