I've had a MBP for a while, but have only recently (as in yesterday!) severed my Windows umbilical and switched my main work machine - IE my dekstop - over to OSX via a 21.5 Imac. I've always used Thunderbird for email on my PC but am wondering if Mail might be best for OSX. Or.. something else? I'd love to hear feedback from you guys as to your preferred email client. I just want something stable, well-integrated and with strong filtering options.
