Commingling Gmail and 5 email addresses you have

Good reasons to commingle your gmail address with up to other 5 emails you may have:
- let's you keep mobile
- common interface -> reduced overheads
- enough space
- gtalk integrated
- fastest webmail interface in the market

I'm trying hard to say kind words about yahoo or windows-live email .. but I can't lie: they are too slow and "viral". So-viral that you can't do a pop-access without putting bucks in. And so slow that I have to upgrade my computer to really see the very-cool interface they have.
