They can't provide competence in a box because there's no free lunch. What would motivated a free e-mail provider would hand you the keys to the castle? If you want this product, get ready to pay for it.

I also think you're placing a mistaken emphasis on data. It's address books, not your data, that provide lock-in on these services. As far as I know, any of them will let you wrest your e-mail from their claws via IMAP or POP. The hard part is telling your contacts to mail you at <address>@gmail.com instead of <address>@hotmail.com

Full disclosure: I recently accepted a job from Google. My opinions on this matter are mine alone and are not based on any confidential information. I forward e-mail from my own domain to gmail. I also run a mixmaster anonymous remailer.
