Hewlett-Packard has four new computers, all with touch-screens. The cheapest of the bunch is the TouchSmart 300, a 20 inch screen desktop that will retail around $900. Next is the TouchSmart 600, also a desktop, sporting a 23-inch screen, and that will sell for about $1,100 (though for $500 more, you can get the version that is able to show video at 1080p resolution). For those not looking for a desktop, there is the TouchSmart tx2 - a tablet computer that will start around $800. And if you happen to be looking for 42-inch touch screen, the $2,800 LD4200tm is your computer.
If you're looking for super-cheap, Compaq (owned by Hewlett-Packard) will be releasing the CQ61z laptop, a 15-inch screen notebook. It doesn't have a touchscreen but it will sell for $399 until right around Christmastime when the price is expected to rise to $499.
Toshiba will release two new Satellite laptops, both with touch-screens. The M505 has a 14-inch screen and should sell for around $950, while the U505 13-inch screen with a "textured finish" will sell for about $1,050.
