(HPQ) has become the first computer manufacturer to release a tablet running
(MSFT) Windows 7 operating system, releasing a model aimed at U.S. business users on Friday, more than six months after
(AAPL) iPad launch.
Microsoft's Steve Ballmer brandished a prototype HP tablet at a technology conference in January, but the top computer company wavered after it bought smartphone maker
Palm, which owns the webOS operating system.
In spite of concerns inside HP about the touch-screen functions of Windows 7, the company later committed to deliver both Friday's Windows tablet and a webOS slate, which executives said will ship early next year.
While a relief to Microsoft, the debut of HP's Slate 500 is coming with little of the fanfare that heralds a significant challenger to the iPad.
The device is designed for companies wedded to Windows elsewhere, especially those that might want to install their own applications, HP said.
"Businesses really wanted to have something in common with the rest of their environment so they could have one
image to work with," said Carol Hess-Nickels, HP's director of business notebook marketing.
In delaying introduction in other countries, HP is forgoing even more of the audience claimed by Apple. That company has already sold close to 8 million iPads, which were designed mainly for consumers but have been adopted by many businesses as well.
Other large manufacturers have so far shunned Windows 7. One
executive criticized it as being too optimized for the mouse-and-keyboard approach of a desktop PC.
Executives at U.S. manufacturer
declined to promise a Windows-based tablet in interviews on Thursday, saying they were waiting to see progress from Microsoft.
Analysts expect Apple to dominate next year's tablet market. The overall market could reach 50 million units by 2013, Dell said.
HP's $800 entry has an 8.9-inch screen, falling between the 9.7-inch iPad and 7-inch devices such as the Samsung Galaxy Tab, due out next month and running
Android operating system.
In the business market, it will compete with the iPad,
forthcoming Android-based Cius, and
Research In Motion's
announced PlayBook, which runs RIM's own QNX operating system.
HP executives said the introduction of a tablet for business using Windows this year did not necessarily mean HP would use Windows just for enterprise tablets and webOS just for consumer media tablets. It plans to use webOS on a variety of devices.
