How can I synchronize calendar/contact data among an iPhone, 1 Mac, and (1 or 2) Windows boxes? I got an iPhone a while back. I'm pleased with it, for the most part. However, I'm not happy with the way it handles information syncing. I'm more used to the way my palm did syncronizing of information -- I could have palm desktop (or, on the mac, some kind of isync software) and all the address and calendar information would be shared between all my computers and my PDA. And a change made on one would be propagated through the rest as the PDA synced with them.

I would like to be able to do the same with my iPhone. In particular, I want to be able to have the iPhone sync with my work calendar and with ical at home.

Here's my setup:
at home, I have a windows box and a mac. the mac has ical and address book and such. the windows box has previously stored address/calendar info in palm desktop. I'm fine with migrating to whatever, there, and might be okay without calendar/address info on it if needed.
at work, I've got a windows box that uses outlook to talk to the local exchange server. itunes can't get to that data, so i assume I need something else to talk to both the iphone and the exchange server. I can't link the iphone directly with an exchange account as my employer doesn't support that.

I don't care if notes get synced among all the devices, and I don't care about to-do stuff or tasks in outlook. I do want my local outlook address book on my work PC to be synced with the address book on my mac, and my exchange work calendar to be synced with ical. And both of those to be synced with my iphone.

The missing sync web page talks about syncing to-do items and notes, not address and calendar data.

Will mobileme do this? Although even at Amazon prices, mobileme is above my price point for annual fees. (And I particularly dislike the fact that mobileme nukes all data it got from the cloud if you drop mobileme, which would add a future de-synchronization of doom).

Is there something else that won't demand an annual fee that will do this? I mean, besides keeping an old palm device around as a sync conduit. (this is actually my current workaround hack for the problem.) It looks like there are several ways to keep the iphone and my mac in sync, but not so much for the iphone/windows-exchange side of things.

I don't care about having a mac.com email address, or sharing and storing pictures/files/websites.
