What's new? Microsoft has been de-bundling software to push more expensive SKUs for awhile. Last year, my friend was very upset that that his new Windows 7 desktop no longer had support for additional languages, he would have to get the Ultimate Edition. It's a very annoying de-bundling for some people because it's a feature that's been there for at least Win95. "Upgrading" to the Ultimate Edition is not exact cheap, plus he would lose out on the extended support of his "Pro" version. I just dropped by his house recently, saw a new iMac. Microsoft pushed him too hard to extract extra money and they pushed him to Apple. His logic was that it cost pretty much the same for a new all-in-one Win7 with Ultimate or an iMac, and he's tire of dealing with Microsoft's bs.
For Windows 15, all we would get is a "C:\" at startup. You want a graphic interface, pay for that part. Oh, connecting to anything else besides the authentication server, gotta pay for that too. Printing, that's going to cost you.
