I really liked the new theme when it was in early development, and so did many other people (clones using KDE/GNOME/Beryl abounded). They've completely ruined it now though.You are, of course, joking.It like Windows, linux, and mac all shoved in together to make one OS.
Aero is fairly obviously Microsoft's answer to Apple's OS X graphics, and possibly Linux' Beryl/Compiz, but other than that I really fail to see the similarities. I don't know if this is still the case, but there's some pretty serious (and thus, since the concept is flawed, seriously bad) DRM stuff in the plans at one point. I suspect at least some of it is still there.
I suppose that could be considered Mac-style too (iTunes &c.), but I think the Linux community would start building its own hardware before it let something like that into the OS Linus' mere mention of allowing basic DRM-supporting hardware in the license recently sent Stallman up in flames.
