The 10.1-inch form factor from the original Asus Transformer Prime continues with the Asus Transformer Pad Infinity, and among the new crop of 7-inch tablets such as the Google Nexus 7 and the rumoured iPad Mini, there's still a lot to be said for having a larger device.

Portability might be compromised, but if you want to browse Flipboard or play a game on the sofa at the end of the day, that larger display will come in handy.

The Asus Transformer Pad Infinity is 8.5mm thin by itself, and a chunkier 17mm when you connect it to the keyboard dock. The aluminium frame is very attractive, and the concentric circle design will throw off the light like spokes on a bicycle wheel.

The only downside to this design, as far as we can tell, is that the grip isn't as firm as when the rear of the tablet is given a slight rubberised coating, à la the BlackBerry PlayBook or Fujitsu Stylistic M532.

The Asus Transformer Pad Infinity is heavier than other tablets – such as the Fujitsu – but it won't cripple your biceps after 30 minutes reading an ebook.

The Asus Transformer Pad Infinity is also a well-built device. The aforementioned Gorilla Glass display will stand a real pounding, and the rest of the chassis feels like it can take the inevitable knocks that occur out on the road.

You won't find any physical buttons on the front of the Asus Transformer Pad Infinity, thanks to Ice Cream Sandwich's soft key arrangement, and even the sides of the tablet are relatively free from clutter. On the left-hand side is a micro HDMI port, next to the 3.5mm headphone jack.

There's also a slot-loading microSD port that enables you to ramp up the storage space by 32GB. Without the microSD, you get 16GB, 32GB or 64GB of internal storage, depending on which model you opt for.

The volume rocker and power button are both located on the top of the tablet, while the bottom is reserved for the Asus proprietary port that connects the Asus Transformer Pad Infinity to either a charger or the keyboard dock.

Keyboard dock

Like previous Asus Transformers, the keyboard dock is the ace-in-the-hole with this tablet, enabling you to turn it into a Tegra 3-powered netbook. The dock locks into place firmly, and to release it you simply flick the switch at the base of the hinge.

Beyond an extra input method, the dock also gives you a full-sized SD port, a USB port and a second Asus port for charging both the dock and tablet together.

The keyboard boasts its own battery that extends the battery life of the Asus Transformer Pad Infinity to around 14 hours.

It should also be mentioned that it is a fantastic keyboard in its own right. The isolation-style keys give you enough travel to be comfortable and Asus gives you as much spacing as possible between the keys.

The trackpad is, understandably, a little on the small side, and using a cursor on Android takes some getting used to. More than once we found ourselves using the keyboard along with the touchscreen for navigation.

Screen

We've touched on the screen already, but it really is the standout feature of the Asus Transformer Pad Infinity, and deserves closer scrutiny.

Firstly, it won't touch the new iPad's mammoth 2048 x 1536 resolution, but for the majority of consumers that shouldn't be much of an issue.

You get crisp, clean 1080p video on the Asus Transformer Pad Infinity, and the colour balance is excellent. The reflective screen will cause you problems if you try using it outside, but then show us a tablet where this isn't a concern.

If we were to gripe, it would be that the connections could be improved. The single USB port is USB 2.0 and, ideally, we'd have it upgraded to 3.0, which would enable us to read/write data to the tablet 10 times faster. Also, we give you 24 hours before you lose the unsecured rubber cap that covers the port.
