Only 2 months ago I wrote that Gmail had hit 4GB, but it was still behind the main crowd (MSN, Yahoo, etc).
Well in time for the new year, they have finally hit the 6GB (not 6GiB yet!) limit. This was initially picked up by a number of bloggers including WikiGiz and BBCentral.
I’ve totally cutover to Gmail since they enabled IMAP and I figured out how to turn it on.
