Comparing the Transformer's performance as a desktop, you can see this system is highly competitive among other all-in-ones in the same price range. Only the Core i7, a $1,349-based system, outperformed the Transformer consistently.
I was also pleasantly surprised to find that the Transformer and its GeForce GT 730M chip can play full PC games with reasonable frame rates and image quality. I had Far Cry 3 running at full resolution and medium quality and the game was thoroughly playable, even during large-scale battles with fire effects and lots of characters onscreen. I wouldn't recommend playing via the tablet in remote-desktop mode to Windows 8, though. The input lag is simply too severe.

As a tablet, the Transformer offers core components similar to those of a higher-end Android tablet from last year. The replacement for the Tegra 3 chip,, should be rolling out to higher-end devices before too much longer, so you might feel some obsolescence anxiety. I wouldn't worry about it too much, though, given the proximity of the Transformer's Windows 8 base unit. The 32GB solid-state drive (SSD) also equals the storage capacity of our current favorite Android tablet, last year's , and the 2GB of memory in the Transformer AIO surpasses that unit's 1GB of RAM.
Of course the Transformer AIO has portability issues introduced by its 18.4-inch display. Given the size and weight of the tablet, 11.5x18.3x.7 inches (HWD) and a hefty 5.6 pounds, I wouldn't give the Transformer tablet to a very small child to run around with. Even an adult holding the tablet upright will notice the weight. That said, the Transformer is easier to maneuver than the nearly 12-pound Vaio Tap 20.
As should be obvious, the Transformer AIO's tablet is not an all-purpose replacement for an e-reader or one of the more common 7- or 10-inch tablets. I can see using it on a couch, in bed, or at a table. Setting it up for the kids to watch Netflix on in another room, or using it as a kitchen assistant, would both make sense. I would not use it in the bathroom, on mass transit, on an exercise bike, or anywhere else where you might need to hold it up for an extended period.
Battery life will also limit your ability to travel with the Transformer AIO's tablet, although it's better than the Vaio Tap 20, I suspect due to the efficiency benefits of Android and the Tegra 3 chip. Asus suggests that you'll see about 5 hours of power watching movies in Android at half brightness, and that matches our test results, which came in around 4 hours, 47 minutes. The Vaio Tap 20 posted 3 hours and 42 minutes on the same test. Interestingly, that's similar battery life to the 3 hours, 23 minutes we saw with the Transformer AIO tablet using Windows 8 in remote desktop mode.
For lighter duty, Asus says the Transformer will last about 15 hours playing MP3s. Our review window doesn't afford us the opportunity to run a 15-hour test, let alone more than one, but as always you should expect longer running times with less-demanding use.
Lastly, Asus equipped both the base unit and the tablet with a reasonable assortment of connectivity options, but with a few holes. The base has four USB 3.0 inputs and a USB 2.0 port that's occupied by the wireless mouse and keyboard receiver, as well as an SD Card slot, and a set of analog audio jacks for a headphone and a microphone. The HDMI output on the base lets you add an external monitor, or even connect to a television. There's no HDMI-in, though, which would be welcome for connecting a game console or a cable box. There's also no separate HDMI output on the tablet, although it does have a Mini-USB 2.0 port, a volume rocker, a microSD Card reader, and its own headphone and microphone jacks.
Asus has obviously put a lot of effort into the Transformer AIO. It is not the most elegant version of the all-in-one/tablet hybrid concept that I've seen, but it might be the most powerful. Its core PC components embody no compromises, and it has impressive versatility with two operating systems and the option to add a second user if you connect an external display.
We will see more variations of this product class in the coming months (, among others), and if the Asus Transformer AIO doesn't meet your needs, another model might. Intel's next CPU generation will also presumably enable lighter, more power-efficient designs before the end of 2013. If it were my money, I would wait to see how the market evolves. For those who can't wait, Asus's design will provide a rock-solid Windows 8 system, and a large Android tablet to experiment with.
