Ok. I've heard all the talk about the laptop dock being like a computer and all but.... Does it work like a computer? I mean can I run spreadsheets, word, powerpoint presentations...etc? Can it do a video out of a powerpoint presentation to a projector? Can I edit powerpoint, word, excel? Can I install other programs on it like I can on a notebook under windows? At the refurb price of 175$ it is attractive now but if it is just a large screen to look at phone apps I don't need it.
