Apple has started selling the iPad tablet in the US, to a blitz of publicity. The UK launch is expected at the end of this month.
Queues formed outside the Apple store in New York with customers eager to purchase the product, which is one of the most hotly anticipated devices since the iPhone was launched in 2007.
The lines were not quite as long as they were for the iPhone, but buyers seemed ecstatic after getting the iPad in their hands.
An instructor at New York University, Matthew Knell, waited in line for a few hours to purchase the device. He plans to use the it for entertainment and to read e-books to replace print textbooks he otherwise carries.
"It offers the opportunity to mix music, movies and books in one good personal-sized package. It does a lot of things the laptops do well, and it has the opportunity to change the way we consume media," Knell said.
The iPads that went on sale Saturday include Wi-Fi, and are priced ranging from $499 to $699, depending on storage capabilities, which range from 16GB to 64GB. Models becoming available later this month will include 3G mobile broadband. UK pricing of all models is yet to be clarified.
The device should be available in the UK by the end of April, Apple has said.
The iPad has been called a supersized iPod Touch, with a 9.7-inch touchscreen and an on-screen keyboard for typing. The device runs on Apple's A4 chip and can play back 720p high-definition video. Apple's iWork productivity application is included for those who wish to create documents, spreadsheets or presentations.
Market research firm iSuppli on Friday estimated that close to seven million iPads would ship by the end of the year.
The device has received positive reviews for its long battery life, multimedia capabilities and e-book reading features. Analysts have also said the iPad could impact content distribution and spawn new ways to deliver video, news and e-books with specialized interfaces.
However, some potential customers argue, that the iPad has drawbacks, including the lack of a video camera, USB ports and support for Flash, which enables video on the Internet.
Julian Scholl, CEO of advertising firm Zum Goldenen Hirschen, said he would like to use Skype for videoconferencing through the iPad. The lack of a video camera affects those capabilities.
But he plans to buy the product in the next month when the iPad is released in Germany as the Apple products are important to the advertising industry.
Many of the buyers lining up to purchase the device were owners of Apple products including the iPhone and Macbook.
Users will be able to connect to Apple's iTunes stores to purchase music, movies and TV shows. Close to 8,500 movies will be available for the iPad, including more than 2,500 in high definition, said Brian Marshall, an analyst at Broadpoint Amtech this week.
More than 55,000 TV show episodes will be available and CBS and ABC will stream shows to the iPad.
Apple is also entering the book and news distribution business with the device. The company is introducing the iBooks application in the App Store for users to browse and buy e-books.
Top book publishers including HarperCollins, Simon & Schuster, Penguin Group and Macmillan will make e-books available through the store.
Electronic textbooks will be available from McGraw-Hill, Houghton Mifflin, Pearson and Kaplan. News and magazine content will be provided by publishers including The New York Times, the Wall Street Journal and Associated Press.
Thousands of applications written for the iPad are already available through App Store. Some notable companies introducing iPad applications include Ebay, Cisco, Netflix and Nuance Communications. Games will be available from companies like Electronic Arts.
Apple is also taking orders for an attachable keyboard so users can type long documents, and a dock for the iPad to function as a monitor. The other accessories include a case, camera connection kit and USB power adapter.
