It's partly inertia and knowing that it would be a hassle to switch email addresses. But also, I think it's a phenomenal service. It's quick, and has great ui. Great spam filters. Great security - recently google added two-factor authentication as an option, which I love, since so many services are tied to my gmail account. In addition they have "shadow accounts" for services that need your password to function (usually other email clients) - so if you setup IMAP on your phone, and your phone is stolen, you can simply disable access for that client. The total package is great.
