Samsung unveiled on Thursday what the South Korean electronics giant hopes will be a major rival to Apple's highly successful iPad tablet PC.
The Galaxy Tab, presented at the IFA electronics trade fair in Berlin, Germany, has a seven-inch (17.8-centimetre) touchscreen, slightly smaller than the iPad's 9.7 inches, and uses Google's Android 2.2 operating system.
"Samsung recognizes the tremendous growth potential in this newly created market and we believe that the Samsung Galaxy Tab brings a unique and open proposition to market," said mobile communications unit head JK Shin.
The Galaxy Tab, weighing 0.8 pounds (380 grammes) - almost half the iPad's 1.5 pounds - launches in Europe in mid-September, and in other markets including South Korea, the US and elsewhere in Asia in the coming months.
But Samsung gave no indication however of whether the Galaxy Tab will undercut the iPad on price, which retails from 499 dollars in the United States - or 499 euros in Europe - for the basic model.
Reports in the trade press said that the Galaxy Tab will be more expensive, at 799 euros (1,025 dollars) in Germany and 699 euros in France.
Apple sold more than three million iPads in the 80 days after going on sale in the United States in April, with demand so strong that some US customers had to wait several weeks to get their hands on one.
Since then, the device, which used Apple's own MAC iOS operating system, has gone on sale in more than a dozen other countries and is poised to hit the shelves in China, the world's largest Internet market, later this month.
The success caught California-based Apple's competitors on the hop, and they have been rushing to respond with their own tablet PCs.
It is rumoured however that Japan's Toshiba will also unveil its own tablet PC in Berlin later on Thursday. Samsung's South Korean rival, LG Electronics, has promised to release a tablet PC using Android before December.
Tablets are smaller both in size and in memory than a desktop, notebook or netbook computer, but are bigger than smartphones, offering users video, music, games, Internet and electronic books - all with touchscreen.
"The biggest market (for tablets) is for leisure. The iPad is becoming the main computer, the first to be switched on in the morning and the last one at night," Joerg Wirtgen from German tech magazine c't told AFP.
"But you can't do everything, only the pleasurable stuff. For lots of tasks you still need a PC or a notebook."
He also said they offered much more than e-readers like Amazon's Kindle.
Gadget website T3 said the Galaxy Tab is "coming for the iPad, and it means business," saying it was on "everyone's 'must see' list" for this year's IFA, which opens to the public on Friday.Reuse content
