I'd want it. I'd like to be able to sit at the breakfast table, and say "Hey Open-Source Siri, is it going to rain today?", "What's interesting on Slashdot today?" and things like that, and it tells me, without me getting the jam on the cell phone. Amazon of course does things like that, but I don't want a black box with a 24x7 microphones in my house. If it were open-source, that'd be entirely different.
