Perhaps. My wife would say so, but she doesn't understand my addiction to genealogy, and consequently, to genealogy mailing lists. After years of having multiple email addresses to sort out my personal email from genealogy email, I've settled on consolidating everything under one email address at Gmail.
Overall, I'm very happy with Gmail, particularly with the fact that I no longer have to worry about space and about deleting old emails. The ability to have 2718 MB of space, and the archive feature have really made this a good choice for me.
My only problem is that because I'm on so many email lists on both Rootsweb and Yahoo groups, that I do not have the time to get through all of the email in a timely manner. But that's a small price to pay to have all of that space, in my book.
