Blackberry Playbook vs. HTC Flyer vs. Samsung Galaxy Tab video review

We look at a trio of 7in tablets and decide which is the best

It could be argued that 7in tablets are the most convenient for general use. They are small enough to carry everywhere, but large enough to be more useful than mobile phones. So we're looking at three of the biggest-selling devices on the market today, with the aim of deciding which is best.

HTC's Flyer has the unique selling point of a pen that can be used to make notes on the device's touch screen. The BlackBerry Playbook is designed to be paired with a BlackBerry phone, and used as a secure extension of RIM's popular business platform. And Samsung's Galaxy Tab is a both a tablet and a smartphone rolled into one, and the only device here on which you can make a phone call.

So which is best? Khidr Suleman and Chris Martin talk about the features and tell you which they would buy with their own cash.
