What a weird way to look at it, would you be happy if your SMS messages were bunched up and sent to you every 1-2 hours? I know I wouldn't and that's the same reason I like my personal mail pushed to me.If the email is pushed then it may use the battery up more than if email is pulled to the device. TBH, unless you use email in a time critical environment then I dont see why anyone has it set quicker than every 1-2 hours... Unless they want to feel important....
