HP Eating Dell Pie. And Lenovo. And Acer...

In a way, computer sales are a zero sum game. The market does grow every year, but if one manufacturer booms, it's usually by attracting its competitor's customers. No one has eaten more of their competitors' pie chart pie recently than Hewlett-Packard.

The news of HP's good fortunes in the PC business came mere hours before HP was set to announce a batch of new consumer and business-oriented notebook PCs at an event in Shanghai. The star of that bunch is the Pavilion HDX, a monstrous notebook with a 20-inch screen aimed at consumers with a heavy appetite for digital media. The launch coincides with the availability of Intel's latest chip platform for notebook PCs. Code-named Santa Rosa, it's the latest product to bear Intel's Centrino brand, which combines the PC's microprocessor with components for wireless Internet connectivity, and which is also aimed at consuming power efficiently to save battery life. Prices for the HDX machine will start at $2,999.

And if that isn't enough, the market for server computers is looking pretty strong for HP as well. Market researcher IDC recently pegged its fourth-quarter server revenue at $4 billion, putting it in second place behind IBM. IBM sold $5.7 billion worth of servers, ahead of Dell and Sun Microsystems, each of which recorded server sales of $1.4 billion.

While Dell is busy worrying about which version of Linux people aren't going to buy from them anyway, Hewlett-Packard runs wild.
