Palm Finally Delivers Real Push E-mail

After many months, even years, of promising an e-mail push technology equivalent to what the RIM Blackberry service offers, it looks like Palm has finally done it.

At least it has come close, with a management component still missing.

Available next week, The Treo 680 and Treo 700p Smartphones will update Palm's VersaMail to include Microsoft Direct Push technology.

Although the push capability was promised via the next Microsoft Exchange ActiveSync Update, the push component of ActiveSync was delayed.

Immediacy of E-mail

The benefits of push over push-like are in battery life and real-time immediacy of e-mail.

Prior to the availability of Direct Push, a device had to remain on and ready to receive a packet from the server, with the server essentially asking whether the user was available to receive an e-mail. The necessity of always waiting for a ping reduces battery life.

Scheduled e-mail delivery also uses power by forcing the system to check for e-mails even when no new messages have arrived at the server.

In contrast, push technology wakes the device up with the arrival of the e-mail.

Difference Negligible

As far as real time goes, however, some industry analysts such as Ken Dulaney, senior mobile analyst at Gartner, claims if a corporate user can get an e-mail within 15 minutes of it being sent, the difference between real push and simulated push is negligible.

"Once e-mail uses a more or less a delivery-activated system as opposed to a periodic check, RIM will no longer have a major advantage," Dulaney said.

Those in the financial services industry might disagree with that assessment.

Direct Push adds other benefits as well. Push as a technology gives the server a remote, control channel. With push, IT can implement a theft loss-protection strategy to delete data or add password policy enforcement over the air.

In addition, cellular companies typically charge more for a BlackBerry data service to allow push e-mail, so Palm devices with an equivalent feature will have a service price advantage.

Direct Push will be available as a free download for VersaMail on Monday.
