Oh, be serious. I still use my @hotmail.com account extensively. I've had it since before MS bought it, so I think it is more a sign of my longevity online than anything else. Most professional software engineers that I know feel the same way. My experience is that people who judge you by your email tend to be very young and inexperienced software folk.
I'm in the same boat as you as far as how long I've been using hotmail. I've been migrating more and more to gmail, but I've got that hotmail account tied to so much shit over the years, I'm not even sure what I'd be losing if I ditched it completely.
