Damian and I are at it again with another indepth review of the Asus eeePad Transformer and this time, we decided to throw as many USB goodies at the Transformer [tracking page] and keyboard dock as possible in an attempt to defeat it.

The USB selection included a Samsung USB keyboard with a trackpoint, a rather ancient looking Microsoft USB mouse, an USB Flash drive, a Sarotech ABIGS multimedia hard disk enclosure and a USB SD Card reader.

This video segment was totally unscripted and thus the we were genuinely surprised and excited that the Transformer worked and functioned with every USB device tested.

This is good testimony that the Transformer and the keyboard dock accessory is a real contender to replace the netbook as most of the common USB devices that we rely on for everyday computing will function on the Transformer.

Damian also commented that Asus will be releasing some useful Transformer adapters (including USB) for the tablet really soon which means you won’t need to get the optional keyboard dock in order to tap into the USB goodness!

The next challenge we had for the Transformer was hooking it up to a LCD TV via the HDMI out connection.

Note that the Transformer uses the mini-HDMI which differs from the Acer Iconia A500 that uses the micro HDMI instead. (If you’re looking for HDMI cables, don’t miss our guide on how to avoid getting ripped off)

There were no issues with getting the display mirroring working albeit a ‘gremlin’ moment when the LCD output display froze — this was rectified by detaching and reattaching the HDMI connector on the Transformer.

We tested video playback using 2 sets of 720p and 1080p video files and playback was disappointing on both the tablet as well as the LCD TV display out – both audio and video were terribly choppy and experience dropouts. This was encountered even after the latest Android system update which promised performance improvements which certainly weren’t evident in the video playback.

The system update did deliver some new cool features such as video editing application but that is review for another day, so stay tuned for that!

Damian was lucky enough to get his hands on an Asus Eee Pad Transformer as well as the keyboard dock directly from Taiwan and we dedicate this video exploring the Transformer’s design and ergonomics with comparisons against an array of others tablets that we have handy at that time, including my beaten up, original Transformer, the HP TC1100 tablet pc.

Overall we were happy with the design and ergonomics of the Transformer and the keyboard dock provides a plethora of connector ports including HDMI, USB, and SD. The keyboard also had an in-built battery which, when docked with the tablet, provided around 16 hrs of useable battery life.

The presence of this battery made the dock almost as heavy as the tablet; the combined weight of the Transformer and dock puts it past 1kg, making it possibly a little heavy to carry around.
