So what? Many, and I do mean *many* people use it on their phones or PDAs, and there is already working source code to support this. Also, many management types extensively use such devices, and if they cannot use them with GNU/Linux then it's just not an option to migrate. We all know people like that who stubbornly refuse change, and if they have to trash their beloved on-the-road companion in the process it's just *not* going to happen.
Just yesterday I read a story that Mandriva is finally going to support this out of the box in their next release:

Check the comments by the person responsible for the Mandriva integration ("AdamW"). Some quotes:
"What I really had to do to make it all work like you see in the video was a succession of minor things. None of them is really hard to fix on its own, but the cumulative effect of all of them is to make this a real slog to do if your distribution doesn't do it for you."
He's even willing to help:
"I'm going to push as many of my changes upstream as possible, and I'm happy to answer any questions any maintainers for other distros have if they try to implement this stuff for their own distro and get into trouble anywhere."
So the code is there, but it just needs some updating and integration. Yes, I've tried to set this up myself, but I'm not a guru and gave up after trying to get opensync, odccm, synce and multisync in line. Plus bluetooth.
I'm frankly amazed that this idea isn't any higher on the priority list. This is the sort of thing that has a real influence on corporate desktop acceptance.
