Let the hive mind of Engadget get that for you.
"We need a digital camera that can be switched on and fire off that first shot fast. It's not a commonly tracked statistic on any review site, and nobody seems to have this information for every camera. We were hoping other readers could inform us as to what small digital cameras can fire off their first pics in under a second (ideally under half a second). It needs to be small, but mostly, just really quick in operation. Thanks!"
I work for a hosted Exchange company and can therefore provide some insight as to the 3 major Enterprise level forms of email that might work for iPhone. Blackberry connect is worthless as it doesn't provide full replication of the Exchange mailbox for non-Blackberry devices (have yet to have a customer that likes Blackberry-connect on their non-Blackberry phones). Goodlink is a "stand-alone" piece of software that utilizes it's own features outside of the host PDA OS and therefore wouldn't integrate seamlessly into the iPhone, so it in effect would defeat the seamless integration of iPhone which makes it a non-starter as well. Licensing Active Synch to wirelessly slip-stream the Exchange mailbox data into the iPhone features (Email, Calendar, Contacts; Tasks--not currently available on iPhone: NOTES doesn't synch wirelessly w/ Active Synch)is the only thing that makes any sense for the iPhone product. Active Synch is built into Exchange server so the licensing is relatively inexpensive (no separate server licensing).
This should be relatively simple requiring only some setup options for Active Synch and possibly creating a TASK application if iPhone was to take advantage of ActiveSynch wireless Tasks (which are rudimentary anyway and hardly worth the trouble). My guess is that Apple wants to create a relatively large "splash" with their first iPhone software/firmware update and providing true enterprise-level Exchange compatibility via Active Synch would solve the biggest hole in the feature set and make for a nice "told-you-so-we-can-update-the-device" announcement for Apple's iPhone upgrade release. As far as I'm concerned, if Apple provides Exchange compatibility first, some of the other bells and whistles can wait.
