There is word that the HTC Magic will be offering Microsoft Exchange Support which will allow users to synchronize with their Outlook emails, contacts and calendar entries. I guess HTC was really thinking of corporate users and since the T-Mobile G1 didn’t have this feature although there are third party apps that does the same thing but however I believe it is better to have it built-in.
But at the end of the day you will have to find an outlet to charge up your phone if you rely on a push connection.
