Sony's tablets have been doing the rounds for a while now, first hitting the rumour mill back in February and then getting official recognition from Sony in April.

Curiously though, they are not hitting the shops with the monikers that you may be familair with - the S1 and the S2. Oh no, Sony has shaken it up and come up with the Sony Tablet S and the Sony Tablet P - both of which have been officially detailed over in Berlin at IFA.

The S1 is the S. You know, the fairly normal looking one but with the curvy bit on the back. It features a 9.4-inch WXGA (1280x800 pixels) TFT colour LCD display and is powered by a 1GHz Tegra 2 chip from Nvidia. It has a 5-megapixel camera on the back and a 0.3-megapixel one on the front for video conferencing.

It'll come in three flavours, 16GB and 32GB Wi-Fi only, and 32GB with Wi-Fi and 3G. The Wi-Fi one weighs in at just under 600g, the 3G functionality adds around 27g.

The P is the new name for the S2 and will feature dual 5.5-inch displays (1024x480). It is a 3G and Wi-Fi number with 4GB of storage. The cameras are the same as the S1, as is the processor.

Both Sony Tablets are running Android 3.1 for the Wi-Fi versions, which we're told is upgradable to 3.2. The 3G versions will come boxed with 3.2. Both tabs are also PlayStation certified as well. The Sony Tablet S includes infra-red technology, and can be used as a fully customisable remote control for all your Sony home cinema machines.

Release dates, but not prices have been confirmed. The Tablet S Wi-Fi version will land in the UK in September, with the 3G one coming in November - the same month that the Tablet P arrives.

Pre-orders for the S being now direct from Sony and also Currys and PC World.
