This is interesting - Apple is hiring people to work on Exchange support in iPhone...
This will, obviously, make the iPhone much more palatable to your corporate IT department...
(This is interesting, because it probably means that Apple has been listening to their corporate customers, for once. It this keeps up, Windows is screwed.)
...but keep in mind that your IT department now has their grubby fingers on your iPhone. From what I've heard, most corporations won't allow employees to sync their phones with Exchange servers unless they support the Exchange 'remote wipe' protocol - If your phone gets stolen (or you left it in a cab after an evening of deal-making and sake) your IT department can wipe it remotely. Yikes!
I don't trust my IT department with that kind of power. But I can understand the corporate security dilemma.
The other interesting thing about Exchange on iPhone is that is validates my opinion that Microsoft employees have been living in a fog for a while:
Every Windows Smartphone owner I know, outside the company, hates their phone - they got lured into buying one on the appealing prospect of having their phone be their digital butler - It sounds great to have a device that wakes you up in the morning, reminds you of meetings, gets your email from anywhere, and allows you to browse the web from the back of the cab (Googling Sake+Strippers+Manhatten)
Instead, what they got it a phone from a shitty also-ran cellphone manufacturer, with a generic Windows OS, tied to a cell company that nickel and dimes them to death. With a alarm clock that works half the time. With an email setup process that is horrendously difficult. With a web browser that is close to useless.
Every Windows Smartphone owner I know, inside the company, loves their phone - because the average Microsoft employee loves to dink around with something until it mostly works.
The alarm clock problem? Jonny Q. MSEmployee researches the problem, downloads the new firmware or Beta Windows Mobile OS off company servers, and great! the problem is fixed.
The email setup problem? Jonny Q. MSEmployee loves tinkering and investigating until he figures out how to get it to work.
The crappy web browser problem? Jonny Q. MSEmployee updates the OS, gets a new browser off the internet, etc, etc.
Jonny doesn't mind all this effort (it's fun! look how much better my Windows Smartphone is now!) but the average consumer? Not so much.
This disconnect has a lot of Microsoft employees thinking that their Smartphones are actually good, and a viable competitor to the iPhone. They are not.
