Well that depends on if you include Android or not and I don't really understand the logic not to.

As far as I'm aware Gnome have never really tried to get in on the phone/tablet space. I'm not aware if there is even a phone that you can purchase with Gnome installed.

Personally, I'm glad I have a phone which I have no need to "sync" with any of my PCs anymore. It just feels very, very old-fashioned.

Playlists can be very useful.

iSyncr and iTunes can do that but I haven't found a seamless solution for Linux yet.

Who gives a damn about these "personal computers"? They are toys for obsessive nerd hobbyists. Some of us have work to do.

Who gives a damn about this "multimedia?" It's all toy sound cards for vidgames and silly fragile CD ROMS. Some of us have work to do.

Who gives a damn about the consumer internet? It's all AOL sex chat and Pez dispenser trading. Some of us have work to do.

Who gives a damn about these "social networks?" It's for sex-crazed drunken college students, child molesters, and shut-ins. Some of us have work to do.

Who gives a damn about this "Linux?" Its a neo-communist academic experiment for people too poor to license a real commercial Unix (TM) or even Windows NT. Some of us have work to do.

Open source tends to work better in mature markets where there is something relatively stable to copy and where there are a lot of players who are incentivized to cooperate and adhere to standards. That's not mobile right now, and by the time mobile turns that corner Android (currently locked down on most installs in a very non Free way) will probably be the open source contender of choice.

From what very little I know about GNOME, it sounds like a great plan. I just happen to think mobile is extraordinarily important and look forward to the day I ditch the iOS platform.

I've been running Ubuntu 11.04 (first release with Unity) for a while as a workstation desktop, and while there are warts that I'm sure are dealt with in 11.10 and 12.04, it's mostly annoyances. Nothing that has seriously impacted my productivity.

Android is doing ok I think. Or do you just mean linux with a gnu/unix userland?

Android is just too good to be Linux. That sort of reasoning.

Yes, you have problems with locked bootloaders and closed hardware on some phones, American carrier-phones in particular. This is bad, but no fault of Android.

That most software on Android, a Linux-distro, may be closed source may sadden a FOSS proponent, but it still doesn't mean it's not Linux.

On my Android tablet I can fire up a terminal, hook up a keyboard via USB and then hack away in a Linux userland, using either supplied binaries, or busybox, or other Linux binaries compiled for the ARM architecture. And it will all work.

For lots of tasks where in the past I would need a PC, I no longer do. Because my Linux-based, mobile platform has me covered. If I want to build my own stuff, I can actually use the normal Linux toolchain to do so. I can do all that because Android, either you appreciate it or not, is Linux. There is no debating that.

And right now Android is dominating the mobile space. I think it's fair to say that Linux, in a form you appreciate or not, has succeeded where your traditional DE based Linux-environment has not.

There's a lot of closed source software for Android and many phones are sold with locked bootloaders.But it's possible to buy those without and google don't care if you root your phone.

So unless your definition is a system 100% open source software that is of no interest to "regular users" (not even Ubuntu qualifies) then this is unrealistic unless you are Richard Stallman.
