Apple iPad 4
Apple surprised everyone by announcing a new iPad and erasing the iPad 3 from memory, adding an all-new processor promising 2x faster speeds

Apple announced a brand-new iPad at the iPad Mini event and in so doing consigned the last-generation iPad, the iPad 3, to the scrap heap.

The new iPad - already being called the iPad 4 - features the same 9.7in Retina display but an all new Apple A6X chip.

The new A6X processing chip promises twice the CPU performance and twice the graphics performance of the last-gen A5X chip.

Apple has added the Lightning connector to the new iPad, a FaceTime HD camera, faster WiFi speeds thanks to support for 802.11n and the addition of 4G LTE support.

Free exchange for your 'old' iPad 3?

And there are suggestions that if you bought an iPad 3 in the last 30 days, Apple might swap it out for a new iPad 4.

Cnet reports some stores in the US are telling customers they will exchange mint condition iPad 3 tablets for the new iPad.

As yet, there is no official word from Apple or on whether this will be the case in the UK but it looks like it's worth checking with your local store.
