Whilst the future of mobile computing may revolve around touch-devices it will be a sad day if ultimately desktops and laptops are replaced entirely, touch-devices are expensive and completely proprietry hardware that cannot be upgraded with ease like desktops and laptops. Touch-devices will never be your one and only device, they are outside of a lot of peoples budget and need replacing by newer and more expensive models each year, whilst I'm happy to use such devices for mobile computing, I don't get excited over the fact that these devices could be the future of computing in general, mobile-computing yes, at least not until hardware stops evolving and raw processing power hits a ceiling, not happening any time soon. For now these devices are for tech-chasing geeks with more money than sense IMO, playing into large companies hands by essentially subscribing to expensive hardware refreshes each year.
