I got a Droid. You'd think out of all the bells and whistles these phones have that you could get email to work the way you want it to. Push email sometimes downloads new mail but usually doesn't work and pull (turning of push and using the fetch schedule) works only if you have back ground data turned on and I'm still not sure that works so well either.
If you want to use pull because push isn't working well, you also give access to the Internet for all the applications that use background data. Dirty little trick. I'm hoping for an update that allows you to turn off background data with the exception of email notifications but I don't think it will happen given the marketing model of the Droid.
