Not clear how it works

Absolutely necessary for The Enterprise, it is not clear to THIS reader how this particular flavor of push email works nor how much power is used up by it.

Its DirectPush, HTTP-based Exchange Activesync push with Exchange 2003 SP2 only, and it uses significantly more battery power than polling and SMS-based AUTD.

You know how you can be on a Yahoo page with stock quotes and every few minutes, the page just refreshes? That is HTTP Refresh. The server keeps a thread alive with the client browser and "tugs" on it to tell the browser to refresh.

ActiveSync on the device in conjunction with Exchange 2003 Sp2 works the same way. ActiveSync connects to the server, syncs, then maintains that HTTP refresh thread. Over time, (15-30 minutes - maybe longer, not sure. never timed it), the server will break the thread at which point ActiveSync will re-establish it. This is called the heartbeat. If, before the heartbeat happens, there are any changes to the user's account that warrant a refresh, Exchange "tugs" on that thread and the device syncs. Changes I've observed that warrant this are a new email or any time you save/create a contact, task or appointment, or anytime you mark a task complete on the desktop. Those seem to immediately get pushed to the device. Marking emails read/unread don't seem to warrant a sync.

It is VERY fast. 9 out of 10 times, when sitting at my desk, my device gets the email before Outlook 2003 does.

And contrary to Surer's opinion, It seems to be much more battery friendly than SMS for several reasons.

1) GPRS is on all the time anyway. An HTTP refresh thread doesn't materially affect battery life.
2) A background sync while the device is off is very battery friendtly. The screen stays off. If the reason for the sync is a new email, then your email alert can have an adverse impact on battery life - the LED, the vibrate or noise. However, SMS push alerts would do the same thing, so that is a wash.
3) SMS alerts would wake the device all the way up, so the screen comes on and the backlight comes on for 30sec-1min that most people have. I found SMS push to be so battery draining I never used it during business hours before MSFP. I set it to 5min sync which was much better. The new HTTP push is better than even the 5min sync as rarely does someone get an email every 5 minutes all day long, so you sync less.

Theory is fine, but I've seen actual tests which show a big battery hit.

Then it must be device dependant. I've had actual experience via use of the K-Jam and JasJar where SMS AUDT was far more battery unfriendly than HTTP Refresh push, to the point at the end of the day there was 20-30% less battery life when AUDT had been used vs scheduled sync. I have had no discernable difference between scheduled (every 5 min) and HTTP Push, so they seem to be roughly equivalent.

Wow....Hansberry propagandizing for MS...shocking!

how major is the update?

joad @ 4/20/2006 9:14:30 PM #

Is this finally the anticipated update that replaces that lousy WinCE operating system with PalmOS?

...if it isn't, nothing to see here....

Notice how Palm Inc. plasters palm.com with only the Treo 700w ads for months non stop. We even saw 700w TV ads, something unheard of for Palm OS device. Now the Windows Treo is getting tons of rushed "major" upgrades and it is taking over Palm OS boards.

1 word: sellouts

RE: how major is the update?

joad @ 4/22/2006 8:05:34 PM #

well, it seems all that Palm has to "sell out" at the moment is a couple of cell phones -

one, a long-in-the-tooth 17-month old minor update to a phone release in late fall 2003

and

the other, a slight redesign of both (with finally more internal memory), but constrained by a lousy Palm-wannabe operating system and long-term single-carrier release with Verizon.

Last time I checked in with Verizon, it would be the LAST company I'd purchase data minutes from, or for that matter simple voice minutes - Waaaaay overpriced. MAYBE if the Treo included an analog radio and I travelled into the "sticks" a lot, but for anyone mainly in a metro area you can't do better with a Treo than Sprint in the US.

Have you used a treo?

stonyboy @ 4/22/2006 12:31:22 PM #

It is not what it was back in the day. It is out dated, I usedto think that Palm was the best and it was back when I would buy things from sony. I has been a long time since 5.0 was relased. I would like to use more then one bt device, not have my calls sent to email when my palm is on the data network. That and it is no longer the benchmark for stabilty! It has gotten old and the only thing that keeps me from getting a 700 is the fact that there is going to be a "750" coming and I dont want to get another half baked device.

Why does the name ring a bell w.r.t. OSes?

Codename Crossbow:

-- http://news.yahoo.com/s/pcworld/20060424/tc_pcworld/125513

Why did some of my memory synapses start firing when I read that?

Hmmm...strange...

[note - my computer side goes back to the early 70s - a name such as "crossbow" for some type of OS-like entity could date back that far!]

RE: Why does the name ring a bell w.r.t. OSes?

PenguinPowered @ 4/24/2006 8:10:04 PM #

it has been used a lot in an OS context. Sun has an open-solaris 'project crossbow' aimed at virtualizing network stacks. There's an embedded sensor project that uses Crossbow. (I think there's even an embedded hardware company by that name.)
