The Economist writes:
The PC has created wealth on a massive scale. The combined stockmarket values of PC hardware and software firms exceed half a trillion dollars. Cheap computers have boosted the productivity of individual workers. And hundreds of millions of people have benefited from access to word-processing, spreadsheets, e-mail, file-sharing and cheap phone callsto say nothing of the riches of the web.
The PC is under threat as the primary platform for which software is written, as software starts instead to be delivered over the internet. You can call up Google or eBay on any device with a web browsernot just a PC. People have been saying it for years, but this could finally allow much cheaper web terminals, or network computers, to displace PCs, at least in some situations.
