Asus has tipped up to the Mobile World Congress in Barcelona with shedloads of new add ons to its range.

On the tablet front there are two additions to the Transformer Pad Infinity Series. Both have 1920x1200 SuperIPS+ display and are powered by a Tegra 3 SoC. Asus' spec says the chip runs as fast as 1.6GHz, with the wind behind it and if it is going downhill.  That is 200MHz faster than the older Transformer Prime's maximum speed. A second version of the Infinity will be available with 4G LTE connectivity and a Qualcomm Snapdragon S4 Krait processor. The  dual-core Qualcomm chip has a 1.5GHz clock speed, while the Tegra 3 has four cores plus a fifth "companion" core designated for low-power operation.

The tablet is the same thickness as the Transformer Prime, and otherwise it is a similar tablet in look and feel. Asus has added a 16GB version to the mix. On the budget front it has added new Transformer Pad 300 and killed off the TF101. This device retains the 10" 1280x800 display of the first Transformer while adding a Tegra 3 SoC. It has dual cameras, Android 4.0 and a keyboard dock, so that you can turn the keyboardless netbook into something more useful. The Transformer Pad 300 is 50 grams heavier than the Prime, which still makes it slimmer and lighter than Asus' first Transformer.

Asus has also released the final specifications for the PadFone Asus. This is a smartphone hybrid which uses an older version of Qualcomm's Snapdragon S4 SoC.  It is still dual core and can run at run at up to 1.5GHz. The 4.3"screen has a 960x540 display resolution, which makes it bigger than the iPhone. Asus claims that the PadFone is slightly thinner than the iPhone 4S and a few grams lighter.

It can also fit into a tablet docking station that offers a much larger 10" 1280x800 display. Asus has been keeping quiet about the price for this lot but given that the company needs to do something to pull its nadgers out of the fire we can't see these being over priced.
