GMail love.
I recently fell upon my very own gmail account. So far it's everything I didn't know I wanted from an email service. So far I find myself using mostly the keyboard shortcuts in the system and just loving the grouping of the emails like below:
So far the conversation has 23 and going strong. This is what it looks like when you pull up the message conversation:
There are so many things I haven't explored yet. I thought I was going to miss the fact that I can't create sub folders to store related emails, but the ability to Label conversations is much much easier. I haven't tried the filtering stuff yet but I'm sure it rocks just as hard as everything else in this system.
So when this go public get an account it's worth it.
