Well, I am not sure it is possible to explain it to you. You don't seem to be capable of comprehending more than two or three lines of reasoning at any single time. Sorry to be mean, but that's how I see it.

But I can try:

Google is making Chrome OS. A web based OS that works pretty much only on the web. This is one part of the future; the web for everything. You hardly need an OS for this, but you need the web. Jolicloud is similar, I have installed it, and it works. I'm not sure I liked it too much, but I'm sure lots of people do. The point is, as long as the web is there, and HTML5 is there, MS Windows has no place in there. There is nothing MS can do to make it better for the user.

MeeGo is similar. But MeeGo offers a total package, not just the web. But it still is Linux, and can use all he stuff made over the years for that platform. MeeGo is hosted by the Linux Fondation, MeeGo is the ultimate Linux distro, it is what all other distros should have been. Most of all, it is a common platform for - everything. It has everything, the web, the core OS, the UX and it works on everything, at least everything mobile. Any open standard can be used, and any closed standard can also be used for the manufacturer of HW. Netbooks and tablets will be sold with any variety MeeGo. They may look differently, they may behave differently, but they will all have the web and everything with it. They will all be able to run 3D games and so on. The manufacturers of HW don't loose anything, the users don't loose anything. What MeeGo does is to cut out the leech, MS and Android for that matter, and channel the money into HW and direct software development for their HW (but there is no need for much software development).

Have to add: MeeGo is an OS for mobile devices, it is not a smartphone OS, but more for devices called smartphone-ish tablets and larger. Symbian is Nokias smartphone OS, (the best OS ever produced, but that's irrelevant here). Unless this is understood, this discussion is hopeless.
