Are you having problems with gMail?
While some of these comments seem to be related to logging on (which I've never had a problem with), I just experienced what I would consider to be kind of a major issue.
I sent three emails to my own other accounts this morning via gMail and none have arrived yet. Granted, this is the Internet and while many of us take instant speed for granted, there may be very many real reasons for the delay. (or, said with my conspiracy hat on, maybe other email systems are purposely delaying gmail mail as an attempt to discredit the service - if so, shame on them!)
However, no problems with receiving emails. Maybe it is a good thing to simply use your gmail account as a "backup" for inbound email.
