That's how it seems to be shaping up from the time that I tried the demo too. But I'm willing to bet that the full OS will be so much more different that the demo, although i only used older versions of the demo so I'm not sure how much changed in the demo as it got closer to release.
In my opinion this is just showing how much Microsoft wants people to jump on with them. Especially when Microsoft said that pirated versions of 7/8/8.1 would get the free upgrade to a legal key.
As i final note what do you think of the rumor that 10 will be the last OS Microsoft will release, and they will just keep 10 in full support over new OS's? I'm not too sure on the truth behind this but it's out there and is interesting.
