I find this amusing and annoying at the same time, I understand when you work you want to left alone but science is all about mingling- sharing ideas, sharing crazy hypotheses, sharing work space and more. I think science would have remained rudimentary if the iPOD was discovered 200 years ago. I am not sure I can embrace the idea of come to the lab, turn your iPOD on and do whatever it is that you might be doing- surfing the net, working on an experiment or reading papers. My old lab was different that way and I liked it- we did not flaunt the "oh-look-wires-coming-out-of-me and so glued to my ears I cannot take it off" thingies. We talked incessantly, our thoughts constantly collided with one another giving rise to better experiments, we would badger the newbies in the lab calling it the "we would love to get to know you" phase.
This iPOD fetish might have something to do with being in a big lab, your bench spaces themselves are so far apart that there is very limited extent of interaction.
Anyway, I think as scientists we should limit the use of such devices- use it albiet sparingly, at least when at work. I am just a fly on the wall but I hope I am making sense here. I think this is not just true about science, you walk on the road all you can see are people either talking to themselves (back in the old days we used to think such people had the crazies!), or talking to a cell phone or concentrating on the music that is playing right into their heads.
So long people...man is a social being afterall, is he not?
