Inevitably, the Kindle Fire HD means there's a new app store in town. Although the Fire HD runs a heavily customised version of Android 4.0 (Ice Cream Sandwich), there's no Google Play store. Instead, Amazon has a curated store of its own, with far fewer apps. The number is sure to grow quickly, and big-name titles are already there, but the Nexus 7 currently beats the Fire HD where games and productivity apps are concerned.

We could compare the Fire HD and Nexus 7 spec for spec, but that's not as meaningful as looking at what you can do on each device. The Fire HD is all about accessing Amazon's massive range of media, be that eBooks, music, movies, TV shows and - now - magazines. Yes, you can play Angry Birds on it, browse the web, and sent email as well, but it's predominantly an Amazon storefront.

The Nexus 7 is more of an enthusiast's tablet, with full access to hundreds of thousands of apps in the Play store. It also gives you unfettered access to the Android operating system, while the Fire HD's locked-down version isn't really recognisable as Android at all.
