Which email client do you use?

Simple question, I’m curious. And explain why. :luigi:
I like gmail but I absolutely despise its web mail interface. I used to use Opera’s M2 client and it was kind of OK but not exactly excellent. So I’ve taken to using Thunderbird and it’s really wonderful. Just one of those apps that are just so neat. It’s pretty, fast, simple, powerful and useful. Interestingly though, I strongly prefer Opera’s web client over Mozilla’s web client (Firefox), which I find to be kind of lacking. And I prefer Mozilla’s email client over Opera’s email client. Haha!
