sprint email compared to windows live push?

[riironman]

I am eating so much battery lately and i am trying to see if i can save some power.
1. live hotmail is HTML and if i migrate my hotmail to sprint email is it the same?
2. is the push email from sprint just as fast?
3. I have aol account that check every hour also , with this be push also on sprint?
4. I saw the sprint 7 beta and i guess you can have 7 email accounts. has this been a battery saver too?

I am trying to see the pros and cons to using the pull from outlook and live push email compared to the sprint email.

I asked this before but i have got no responses.
