First shipment of Microsoft's 32GB tablet sells out

If the Microsoft Surface is on your holiday wish list, you might want to place your order now.

According to the Microsoft online store, the RT tablet's £399 32GB model (without the Touch Cover) sold out in a day. It is now scheduled to ship "within three weeks."

Pre-orders for the two remaining devices - the £479 32GB and £559 64GB, both with the black Touch Cover - are still expected to deliver by 26 October.

Microsoft did not immediately respond to a request for comment about the shipping delays, and provided no further details on its website.

Microsoft started accepting pre-orders for the RT version of the Surface tablet this week. Touch covers are available separately for £99.99 each in black, white, magenta, cyan, and red.

The pressure is on for the company, which will release its Windows 8 operating system on 26 October. Several days later, it is hosting a Windows Phone 8 launch event in San Francisco. ITProPortal will be covering both events, so stay tuned for all the details.

Limited pre-order supplies are common amongst highly anticipated products. Last month, the iPhone 5 sold out of its initial inventory in just one hour, topping two million orders within a day and pushing delivery dates to two weeks. Many iPhone 5's ended up arriving earlier than expected, though.

Meanwhile, the 16GB version of Google's Android-based Nexus 7 tablet was out of stock less than a month after its release, leaving only the smaller 8GB available for purchase through the Google Play store. About a week later, the Asus-manufactured tablet was back on shelves.
