Apple has announced it sold more than three million iPads over the past three days, marking a very successful debut weekend for the new iPad mini and fourth generation iPad. The company noted this is double the previous first weekend milestone of 1.5 million WiFi-only models sold for the third-generation iPad back in March -- though factoring in the cellular equipped versions that number grew to 3 million as well.

According to Apple’s press release, the Wi-Fi + Cellular versions of both iPad mini and fourth generation iPad will ship in a few weeks in the US and in “many more countries” later this year.

Unfortunately, the Cupertino-based firm did not share a breakdown of the sales numbers between the mini and full-size iPads. But  the wording of the announcement suggests that consumers favored the iPad mini this past weekend. Apple CEO Tim Cook said the company is “practically sold out of iPad minis,” and he noted they are “working hard to build more quickly to meet the incredible demand.”

The iPad mini was announced on October 23rd with pre-orders going live on the 26th and shipments starting November 2nd. The device maintains the same 1,024 x 768 resolution found on the iPad 2, but the smaller screen translates to a higher pixel density. It also packs the same dual-core A5 processor, improved front- and rear-facing cameras, and is the most portable at 0.28 inches thick and weighing 0.68 pounds.

Available in black and white, pricing starts at $329 for a 16GB Wi-Fi only model, $429 for a 32Gb model or $519 for 64GB of storage. Models with LTE connectivity cost an extra $130 for each tier.
