I'm always surprised when people have email accounts at Hotmail. I associate Hotmail with being a teenager and getting lots of spam. I still have an account with them, but I only use it in places where I think I'll get spammed.
I wonder, is the choice of email provider as conscious a choice as which trainers, or which car. Does having a .mac account say the same things about you as owning an Apple computer? By using Gmail, do you say you are forward thinking or happy to give over your data? Does having a Gmail account say less now that everyone can have it? Rather sadly, I'm glad that I got my Gmail account before it became GoogleMail, because it looks nicer written down.
Or do people use the first webmail they come into contact with and keep using it? And does no one except me look at your mail provider and form an assumption about you?
