Gmail's 1GB of space is pretty awesome and sure beats the snot out of Hotmail's 2MB and Yahoo!'s 4MB. Today, Yahoo! struck back.
They're boosting their free account size from 4MB to 100MB effective today. The hope is 100MB will be enough to stop Yahoo! users from making the jump to Gmail when it becomes available to the general public.
I've been beta testing Gmail all week and it's not just the 1GB that impresses me. Handling emails back and forth as conversations makes email management simplier and using labels instead of folders as a means to group together a variety of messages is genius. Also, the web interface is super slick. The reasons to make the switch are many and not just because you get an entire GB of space. I'm very impressed by what I've seen thus far.
