Tell me about it...
They never really say anything useful about these in these descriptions. If they start linking MS technical pages, etc...heck that confuses IT pros, forget about normal consumers. They just won't buy it until they "figure out what it says"...which is never.
You have to like dig info up from all over the place to see what other people "translated" that hopefully gives you a hint of how it applies to "the real world".
At least these days there are some guru blogs (some who work for MS and can actually communicate and not just code) to help out in this regard. But it's still a real hassle for the average person to find because they won't know what to look for to begin with.
Perhaps it takes better marketing...or those details are best left for the pros to figure out.
