I have a Gmail account. I have a Market account, I think I have a Picasa account, and I have a Blogger account. They are all tied to Gmail. If I use the PC, no problem. One password. Why in hell when you have all this, Google has the right info in market, so it has phone #, carrier, and wtf else, does it need an SMS account for mobile Blogger, too? Google can't figure out who you are from your Mail/Market account? Both Tablet and phone are registered!
