I also want to merge accounts, which in my minds means that there really is just one account with several names--emails to all of them go to that one gmail (and it lets me choose which to send from), I can sign into all google services with any of those accounts, etc.
It would be pretty complicated though. I've only used gmail on my secondary accounts, but some people have probably used docs, voice, etc on multiple accounts, in which case all of those need some kind of merging strategy.
I do that with only one secondary email that generally wouldn't get any emails from real people, so in most cases, I'm covered. But you're right: that technic should come with a warning: you might lose your emails.
I suppose another way to go around might be to retrieve account B through POP or IMAP.
I personally like this option as I can download and delete all emails off google's servers. My passwords are pretty good, but not great, and if a hacker was able to download ever message I ever sent. :(
Didn't know about the incognito trick until today though... I suppose that would have helped quite bit as well.
