As much-rumoured in the last week, Apple has now officially introduced a 128GB version of its fourth generation iPad - iPad with Retina display.

Featuring the exact same specifications as the current model, but with double the storage capacity of the former top-end model, the 128GB iPad has an A6X dual-core processor, 2048 x 1536 resolution 9.7-inch Retina display (264ppi), and 5-megapixel rear-facing camera capable of 1080p video recording.

The front 1.2-megapixel FaceTime camera is capable of 720p HD video. Siri is on board and the tablet features Apple's Lightning connection.

Focused at the more business end of the market - and heavy content users - the new 128GB version will be available in both Wi-Fi and Wi-Fi + Cellular models, with the latter able to connect to EE's 4G network if you sign up for that particular data plan.

"With more than 120 million iPads sold, it’s clear that customers around the world love their iPads, and everyday they are finding more great reasons to work, learn and play on their iPads rather than their old PCs," said Philip Schiller, Apple’s senior vice-president of Worldwide Marketing.

"With twice the storage capacity and an unparalleled selection of over 300,000 native iPad apps, enterprises, educators and artists have even more reasons to use iPad for all their business and personal needs."

The new models will hit Apple Stores in the high street and online from 5 February. The Wi-Fi version will set you back £639, while the Wi-Fi + Cellular model will be £739.
