I hate to dredge up an old e-mail, and please forgive my ignorance, this is probably an easy - or obvious - question.
When I think of Blackberry, the one advantage it has is that it is (at least I thought) the one handset with true push technology that is both 100% up to date and also very easy on the battery.
Other people at work have Android phones using activesync with their email accounts (some with 1.5/6, a few with 2.1) and they have to set their phones to manually update their email because it drains their battery too much to have their emails always updated. So, here are my questions:
1) Is the Android/Activesync link as efficient as the BES/Exchange link for delivering push e-mails?
2) If not, then what are the differences? Is Android "true" push technology?
3) Is there any difference between this feature in 1.5/6 and 2.1? I think most people I know disabled the feature when they had 1.5 and never turned it back on when they upgraded to 2.1.
