Pete,
That is what I though you meant, the gray does not bother you but wanted to be sure.
The gray icons in the side bar are really the least of it, it used to be easy to tell when a menu item was grayed out, now it is so close in shading it is hard to tell.
Add to that all the connection issues (if you have not had any, lucky you), next is trying to troubleshoot issues. The user Library now needs a third party hack to see. I understand that many people need a nannie, I am not one of them.
Just like what Apple did to iMovie, it stinks, Final Cut? Apple wised up on that one and rewrote it to Final Cut Pro X. Good thing too, many were very close to tossing Macs and Apple for Adobe and Windows.
Pages, Numbers and Keynote were successes and translate well to the iOS as does iMovie in iOS form.
Apple has done many users a disservice with Lion and some software, insulting really.
Let users make up their own mind whether to have color icons and user Library. If a user screws it up then let the user deal with it.
Macintosh was color when Windows was gray, Macs were point and click and Windows was DOS. Now Macs are gray and ugly, Windows has stayed true with color where it belongs.
I can't stand Windows, they make everything way harder than it needs to be, Apple is now following but being subtle about it.
I really don't like the 'Get Lion or No iCloud' except if you have Windows in many of its flavors.
I am a long time Mac user, 1989 is when I started, I know them inside and out from system 6 to now, Copland was much nicer than Lion for pretty.
Mission Control (bad joke), Launch Pad (what were they thinking, hangover day?), reopen all windows or apps on restart (what?) like I want all I closed to reopen.
I guess we can attribute a lot of this to Al Gore.
Oh and Pete, I see you have over 1,000 points so you are here a lot and post often, I don't as I don't have the time much.
You sound like you have seen many versions of OSs and you find the gray to be OK, that is a deal breaker for me along with all the other junk. Color gone to save a few KB of code? Put a smaller gas tank in your car to save weight, really shortens the legs though.
