Apple has published its customary first-weekend sales figures for its new iPads, revealing that it shifted 3m iPad mini and fourth-generation iPad devices over the last three days.

The company notes that this is “double the previous first weekend milestone of 1.5 million Wi-Fi only models sold for the third generation iPad in March”. So now you know.

That slightly awkward comparison is because Apple won’t be shipping the Wi-Fi + Cellular versions of its two new iPads until later in the year, hence no like-for-like comparison to March, when the company also announced that it had sold 3m third-generation iPads in that device’s first three days.

“We set a new launch weekend record and practically sold out of iPad minis. We’re working hard to build more quickly to meet the incredible demand,” says CEO Tim Cook in a statement.

Apple elaborates on that, explaining in its press release that “demand for iPad mini exceeded the initial supply and while many of the pre-orders have been shipped to customers, some are scheduled to be shipped later this month”.

The two devices are available in 34 countries so far, with more to follow by Christmas.
