Very nice, sir. I do science for living, and know a little bit about it, but I try not to comment on the field I don't know deep. But one thing I can tell for sure (or at least in a general sense) is, it is much harder to prove something "doesn't exist" than to prove something "do exist" by experiemnts in science. So, yeah, who knows what happens in the next 100 years in science. Somebody may show synaptic ends releases molecules called "xxx" in response to 20MHz ultrasound wave, which has an impact on music perception....things like that. And, also thanks for Android suggestion. Yeah, I've been looking at that too. Particularly, I'm interested in Skype mobile which allows me to show my backyard here to my mom 5000 miles away, who survived WWII in her teens. Unfortunately my dad passed away few years back, without seeing these tech stuff developed by former enemies (that's what he always told me) and benefit of seeing talking with his son over the screen. I might buy Droid for my son when he goes to college, so that I can "police watch" what he's doing?? No, just to see his face, you know.
