Apple iPad to go on sale on 3 April in US and 'late April' in UK

Apple yet to provide details on UK or international release dates, selling prices or associated mobile network companies
Apple's touchscreen iPad tablet computer will go on sale on 3 April in the US, but no specific date – beyond "late April" – has been given for its release in the UK and other international locations.

The company declined to set either the selling price for its models abroad, or to name any of the mobile network companies that will be providing connectivity for the more expensive iPad systems, which have 3G data sims built in.

US customers will be able to pre-order the iPad, which Steve Jobs described as a "magical and revolutionary product", from Friday 12 March, either online or in Apple's retail stores.

The devices come in two basic forms – with Wi-Fi wireless connectivity, and with both Wi-Fi and 3G mobile connectivity. However, only the Wi-Fi versions will go on sale on 3 April; Apple said only that the 3G versions will be on sale in "late April".

All the versions of the iPad will go on sale in the UK, Australia, Canada, France, Germany, Italy, Japan, Spain and Switzerland at the same time.

The iPad has excited huge interest because it expands the interface of the iPhone, Apple's hugely successful mobile phone, into a usable "slate" computer with a 9-inch screen. A number of content publishers have thought that it could be a completely new medium for sales of various products – including electronic versions of books, magazines, newspapers, music and films – that they will be able to charge for by selling them through Apple's iTunes store, which has been a source of revenue for music, film, TV, audiobook and notably "app" creators.

In the US, the basic iPad model with Wi-Fi and 16 gigabytes of storage will cost $499. Apple says that it "lets users browse the web, read and send email, enjoy and share photos, watch videos, listen to music, play games, read ebooks and much more". The device is 0.5 inches thick and weighs 1.5 pounds – "thinner and lighter than any laptop or netbook" and Apple says it can run for up to 10 hours on a single battery charge. (Tests on other products suggest the figure may typically be only half that.)

In the past few weeks there had been mounting speculation that there were production problems at Apple's factories in China. Apple had no comment on that, but the staged release to the international market compared to the US – which makes half of Apple's sales – suggests it is husbanding its resources.

The announcement notably does not offer any pricing for the UK, nor any details about which mobile carriers Apple might sign up with. O2, Orange and Vodafone already offer its iPhone, but none of them are mentioned in Apple's announcement.

Nor is pricing – which could be key to how well it sells. Since the announcement of the iPad in January, the pound has slipped against the dollar in international exchange markets, which has led to speculation that Apple is waiting until the last minute to announce the price in order to minimise any losses on exchange-rate volatility. Macworld magazine, which calculated in February that the low-end iPad selling for $499 in the US might have a starting price of £388 in the UK, recalculated on Friday that the downturn in sterling would now mean a minimum starting price of £400.
