Fujitsu introduced its line of Windows 7 laptops for the U.S., including an ultra-portable model, a netbook, and multi-touch convertible tablet PCs.

The new systems, unveiled Monday, are scheduled for availability starting on Thursday, when Microsoft plans to release the latest major version of its operating system. Starting prices for the PCs range from $450 for the M2011 netbook to $1,199 for the LifeBook T4410 convertible tablet.

Fujitsu's latest multi-touch, convertible tablet PCs include the Lifebook T4410 for mobile professionals and the T4310 for consumers and students. The systems have many of the same features. Each weighs 4.2 pounds and is available with a 12.1-inch LED backlit display with wide-viewing angles and an Intel Core 2 Duo processor. The T4410, however, can be downgraded from Windows 7 Professional to Vista Business or Windows XP. Starting prices are $1,199 for the T4410, which will be available this week; and $1,099 for the T4310 after a $50 mail-in rebate. The latter system will be released Oct. 30.

The LifeBook A1220 laptop is a desktop alternative with a 15.6-inch display, Intel Core 2 Duo processor, 4 GB of system memory and a 500 GB hard drive. The system comes with integrated Bluetooth and Wi-Fi, four USB ports and a 2 mega-pixel Web cam. The A1220 is scheduled for release this week and will have a starting price of $749.

The LifeBook P3010 ultra-portable laptop has an 11.6-inch diagonal display, full keyboard and a 1.6 GHz Athlon Neo processor from Advanced Micro Devices. Other specs include up to 4 GB of system memory, a 320 GB hard drive, integrated Bluetooth and Wi-Fi, a built-in Web cam and three USB ports.

The P3010 is just over an inch thick and weighs 3.5 pounds. While heavier and thicker than ultra-portables from other vendors, the Fujitsu portable carries a low price of $549. The P3010 is scheduled for release in mid-November.

Finally, the M2011 netbook has a 10.1-inch display and an Intel Atom 280 processor. The mini-notebook ships with the Windows 7 Starter edition, 1 GB of system memory, a 250 GB hard drive, embedded Bluetooth and Wi-Fi and a six-cell battery with up to six hours of battery life. The new laptop is scheduled to be released this week, priced at $450.

Fujitsu is just the latest of several computer makers to announce Windows 7 systems in preparation for Microsoft's release of the OS. Most of the manufacturers are including systems with multi-touch displays that take advantage of the touch-screen capabilities in the OS. Other vendors include Acer, Helett-Packard, Gateway and Sony.
