And that's also the worst thing about Google or any web based tool. There's a layer of abstraction with a web based tools versus native.
You're confused about how Google sync works on phones. It's not just for web based access, although that's available too.
Google licensed ActiveSync, so calendar / contact / email data automatically syncs back and forth between all your phones and your free Google account.
In address book or iCal that data is part of a systemwide API that any 3rd party developers can access. ... (snip)
That's exactly how it works on every phone with Google sync. The data comes down and is available to all the native apps, whether the phone is based on iPOS, WinMo, WebOS, Blackberry, Android.
Which is why I'm asking, since I don't know: does MobileMe also use a version of ActiveSync that can work on any phone?
It is worth spending money to decentralize where all my information is stored. Yes.
I like that too. It's free to do so on Google. At least as far as email, contacts, calendar info, and some free picture storage via Picasa. I'm just curious as to what else MobileMe gives for $100 over what Google gives for free.
