The demonstration saw a modified version of Acer’s Liquid E2 smartphone being hooked up to the Extend dock using an MHL cable, although Acer representatives did mention that a market-ready version could eventually arrive with a retractable cord in tow, although we are not going to rule out the possibility of a wireless, Bluetooth-based solution either. The Extend Dock comes in handy if you want to be even more productive with your smartphone, but do not really need the full power of an Ultrabook to get the job done. In a nutshell, it is pretty much a niche market this, but those with enough disposable income might be able to add this to their growing gadget collection. Do you think that this niche device will be able to take off?
