It's not niche, but on the day of release, it's still quite bleeding edge. It's already been discussed here multiple times that most distributions are fairly conservative about new hardware and tend to wait at least 6 months for inclusion.

Well how many people buy Sandy Bridge client CPUs for Linux in the first quarter? 10? 100? 1,000? 10,000?

How many people buy Sandy Bridge client CPUs for Windows in the first quarter? 100K, 1M, 10M?

Linux has always been a second priority for consumer systems. Why do you think AMD's OpenCL support came out for Windows first? Because that's what most people use on Llano or Zacate, or any other consumer notebook/netbook/desktop chip.

It's simply because Linux consumer volumes are 100-1000X lower than Windows.

Linux is nobody's OS, and everyone's OS. It hardly belongs to Intel.

How many desktop or notebook systems do you think are sold with Meego?

Like I said - all it means is that Mike Larabel couldn't get the drivers to work. Other people clearly did...albeit in 2D mode.

At least one person had working drivers for 2D graphics. That sounds to me like at least some of the drivers were 'functional'. Now perhaps the 3D acceleration drivers were not functional, but that's an entirely different kettle of fish from 'not having working drivers'.

I'm perfectly aware there were no pre-packaged drivers.

If you don't like the pre-packaged drivers (e.g. because they don't exist), you can always compile your own.

Getting desktop graphics acceleration working and getting functional drivers are two different things. If you want to complain about non-existent 3D support, I'm on board with you.

However, it's equally obvious to me that the 2D drivers are functional and work correctly.

And when it comes to Linux, I only really use it for servers.
