I currently use Sparrow but I am a bit tempted to give Lion's revamped mail a try. I currently use both a gMail and a Google Apps account for my business and I got them hooked up via IMAP etc. Got a few questions: It appears it is actaully threading my converstion correctly, anyone else having any issues? This was the #1 reason I went to gMail to begin with What are these numbers? I cant for the life of me figure it out? Any reason to use gMail or Sparrow over the new mail? Thanks much!
