The Samsung Galaxy Tab, the South Korean electronics giant's answer to the iPad, is coming to the United States next month at a price more expensive than the cheapest Apple tablet computer.

Samsung and US wireless carrier Verizon said Wednesday that the Galaxy Tab will go on sale in the United States on November 11 and cost 600 dollars.

Verizon Wireless is offering a monthly Internet access plan for the Galaxy Tab beginning at 20 dollars a month for one-gigabyte of data.

"This is an incredible time in mobile technology, and as a company we're excited to add the Samsung Galaxy Tab to our portfolio," Marni Walden, vice president and chief marketing officer for Verizon, said in a statement.

The Galaxy Tab, which is powered by Google's Android software, features a seven-inch (18-centimeter) touchscreen - smaller than the iPad's nearly 10-inch (25-centimeter) display - and supports Adobe's Flash video software, which is barred by Apple from running on the iPad.

The Galaxy Tab also features front- and rear-facing cameras. The iPad does not have a camera.

At 600 dollars, the Galaxy Tab is more expensive than the basic iPad, which costs 499 dollars but offers only Wi-Fi connectivity. The cheapest iPad featuring Wi-Fi and 3G connectivity costs 629 dollars.

Apple chief executive Steve Jobs slammed seven-inch tablets on Monday saying the screen was too small and the device would be "dead on arrival."

"The seven-inch tablets are tweeners, too big to compete with a smartphone and too small to compete with an iPad," Jobs said.

He suggested makers of seven-inch screens "include sandpaper so users can sand down their fingers" to be able to tap tiny onscreen keys.

Jim Balsillie, co-chief executive of Canada's Research In Motion, the maker of the Blackberry which also plans to market a seven-inch tablet computer, the Playbook, fired back at Jobs's comments on Tuesday.

"We think many customers are getting tired of being told what to think by Apple," Balsillie said in a blog post.

"For those of us who live outside of Apple's distortion field, we know that seven-inch tablets will actually be a big portion of the market," he said.

US wireless carriers AT&T, Sprint and T-Mobile are also expected to sell the Galaxy Tab, one of a number of tablet computers slated for release by global electronics companies in a bid to challenge the iPad.

Verizon is also to begin selling iPads this month featuring Wi-Fi connectivity to the Internet.

Verizon said it will offer "bundles" that pair iPads with Mobile Hotspot devices that link to the Web using the carrier's 3G wireless network.

Apple said Monday that it sold 4.2 million iPads last quarter.
