We’ve got more acronyms than we can hang an alphabet on these days when it comes to mobile devices, so why not create another one. The MTube is a sub-5” inch screen media player the Tim Brown at UltraMobileLife.com is labeling as a new class of mobile device called the IMP. That’s short for Internet Media Player for those playing the acronym game. He’s posted up a video of the recent launch event of the MTube for all of those with an impish curiosity about this. The MTube is still aways off, with a target of 2009.
