I haven’t been a fan of Google Apps since they cut back the free version’s features and made it nearly impossible to sign up for and maintain (especially with the pointing of nameservers). I also had no idea there even -was- a paid version of Yahoo mail… people pay for email? Really…? O.o

Merging all of my email accounts into Gmail, was the best thing I ever did for productivity and general email management. Hotmail was an annoyance for a while, but they finally brought back POP3 access, making my single inbox complete. I still log in to Hotmail periodically though, as I tend to use it for my junk account and crank the spam settings. :D
