In advance of the consumer release of Windows 7 next week, HP on Tuesday announced 11 new desktop and laptop computers loaded with new features such as multi-touch, tilting Webcams, new keypad designs, improved power management, the ability to connect to home gaming systems, and even a drain for spills.

Multi-touch is a big part of HP’s new line-up. For example, HP is upgrading its TouchSmart tx2 consumer tablet, which the company unveiled late last year. The multi-touch tablet allows users to interact with the PC either with the included stylus or with their fingers. The twist display allows users to use the laptop in a PC mode, to flip the display to show something to others, or in a more stereotypical tablet mode. The laptop, like the rest of HP’s line of touch products, will come with applications found on the HP TouchSmart PC. It starts at $799.

Another new multi-touch laptop, the DV3, is a traditional laptop rather than a tablet, but for now it’s only testing in Europe.

The company is also releasing two new TouchSmart PCs, the 300 and the 600. Both continue down the multi-touch path started by previous iterations, and include new multi-touch applications from Hulu, Netflix and Twitter, among others. The 300 gets a 20-inch screen, while the 600 gets a 23-inch screen. Select models of the 600 will be able to connect to the Xbox, PlayStation, and Wii via HDMI or composite video. The 300 starts at $899 and the 600 at $1,049.

HP is also launching a slate of new business-focused PCs, including one with multi-touch, the TouchSmart 9100 Business PC, which follows up on the TouchSmart DX9000. It will roll out in December. Pricing is to be determined, but the current model starts at $1,299. Unlike the current model, the 9100 will be customizable. It will also be shipped to businesses with the USB and other peripheral ports locked down and will have solid-state drives as an option, as HP expects companies to use the 9100 in customer-facing environments such as hotels where security and power savings are key.
