Great stuff. I wish the free version of Yahoo mail had POP3 access. I use my old Yahoo account for incoming “bacon” email, and it would be nice to have Gmail pull that in. I do have about 3 or 4 accounts coming into Gmail right now.
I also use Gmail via Goolge Apps. There is a whole process to go through if you have your own domain, where you can point nameservers to Google Apps, which will get rid of the whole “via firstname.lastname@example.org” stuff, but that might be an article for another day. :)
