"both are Ipad killers"
I'm afraid not. For the moment iPads dominate the tablet market, and rightly so - nothing comes close in terms of design and useability. The Motorola Xoom is a promising rival, but right now it has nowhere near the style and panache of the iPad 2.
I was one of those who said 'iPad? Not likely!' a year ago, but now I freely admit I'm a convert. I had to do some research on tablets for a client, and the iPad came out a clear winner. I acquired one a few days ago, and already I'm completely hooked. It comes very close to being the perfect mobile computing device as far as I'm concerned. I have a T-Mobile SIM onboard, so I can access the web anywhere there's a T-Mobile or Orange signal, or a wireless connection.
