Considering you can find the AT300 online for around £310, it's good value. The ability to increase storage or simply view your photos via full-size SD card is nice, and performance is good. The screen isn't the best we've seen, although it's far from bad, so if you're specifically after a 10-inch tablet, you won't be disappointed. If you can live with a 7in screen, the Nexus 7 has the same resolution and processor for considerably less cash.
At 8.9mm thick the Toshiba AT300 feels solid and well-balanced. At 593g it's roughly the same weight as an iPad 2, but is considerably heavier than a 7in tablet such as the Nexus 7.
From the front, it looks like any other generic 10in tablet as there's no Toshiba branding. In fact, apart from the front-facing camera, it's devoid of features.
Power is delivered by an Nvidia Tegra 3 T30SL quad-core processor, running at 1.3GHz. It's paired with 1GB of DDR3 RAM. Naturally, this combination makes for a slick experience when swiping between Android home screens, and also when playing HD video or the latest 3D games, too.
The screen has 1280 x 800 pixels, which puts it on a par with the highest-resolution Android tablets. It's no match for the iPad's retina screen of course, but let's not forget it's considerably cheaper.
The front-facing 2Mp camera provides adequate quality for video chats, but you wouldn't want to use it for any serious photography.
