Despite not being the first name you'd think of when considering an Android tablet, Kobo impressed with its first Arc tablet 12 months ago. And now, Kobo is back, and stepping up to the 10-inch mark with this, the Arc 10 HD. As with the previous generation Arc, the Arc 10 HD is still a reading focused tablet. Kobo is after all an e-reading company, and so it's sticking firmly with what it knows. On the top there's the latest version of Kobo's custom UI, but as before underneath is a pretty much untouched Android 4.2.2 experience with some pre-loaded apps and a few minor tweaks.
