The killer app for the Kindle Fire is Amazon itself, and on that front it delivers. It’s very easy to get hold of your Amazon ebooks, music and video, as well as magazines and TV shows, and there’s a huge selection. Apps are much thinner, though: the Kindle Fire uses Amazon’s app store, not the Android Market, so there’s around 10,000 titles compared to Android’s 300,000-plus.

We’re wary of the phrase “iPad Killer” around these parts, because many of the tablets so described haven’t dented the iPad at all: they’ve been aimed at different markets, at different prices, with different kids of content. However, if rumours are correct and Amazon’s sniffing around HP’s WebOS, we might have to dig the term up after all.

We’ve already given you the heads-up on Amazon’s super-secret Kindle tablet and now details are starting to emerge.

Of all the tablets to be announced in the last few months, Motorola’s Xoom is the one most often described as an iPad killer – and it’s the first tablet to ship with the tablet-friendly Android 3.0 Honeycomb release.
