Cool, I would be curious to hear any opinions on those! Has anyone heard about this company before?

Once I'm back from Vancouver (next week), I'll probabely go ahead and buy some of the 15m data for The Netherlands. I'll be able to post a review of the data then.

Are you going to ground-truth it too... ? 
I bet it is really good and detailed, but I doubt that the development and classification process is as transparent, rigorous and (quality-)controlled as GLC2000 e.g.
But I'd be happy to be proven wrong on that one! For the true-color image, those things are of less importance, but for the land cover classification I would approach it more carefully.
Not that those aspects would scare me away, I already know of applications where I would use the 250m free dataset!
