This didn't make sense to me. Please rephrase?

3) There are no major upgrades to vista from xp besides the graphics which is not needed it is just a way for them to make companies who want to make software for it pay for a license and get more money from you. If you look deeply into Windows 2000-Vista they are all exactly the same features except for how it looks, and up from windows 2000-xp some backend fixes which can easily be done by upgrades if you think about it.

Wrong on many levels. As already stated by others, there are many (thousands) of underlying changes to the Kernel and other areas that you perhaps won't ever notice. Just because you can't see them, doesn't mean they're not there

The jump from 2000 to XP was as "significant" as XP to Vista, in terms of underying code changes.
