> I mean, lots of points for cool factor, just not sure how many points for utility. If the dock can be really inexpensive and phones get a little more capable
I think it's a given that phones are going to get a lot more capable
as for the dock being inexpensive, for my tablet, all I need is a HDMI cable and a keyboard (either USB or bluetooth), how much cheaper do you need to be?
the other advantage is that if you use your android device as your computer, you can use a public dock without any real worries about malware stealing or destroying your data (yes, someone can make a malicious keyboard or mouse, but that's a targeted attack on a particular physical location, not something in the same class as what can happen to a public use desktop machine)
