Really? So what are all those options in the System Preferences tool that let you change things?
It's really not enough. The mindset of OS X and the app ecosystem is broken from this point of view. Most apps have 5 to 10 times less options than their Windows or Linux equivalents. If most people don't need to fine tune applications that doesn't mean that ALL people don't need to do that. Usually power users and content creators will need to do that in order to be more efficient in their work. If you want just to consume content then the Mac is just fine, but then again, you can do that for less money with an iPad or an Android tablet.
It's not that you're trying to configure OSX to be like Windows is it?
No, I'm trying to make OS X sane. I'm in no mood now to make a list with all its design flaws and problems. These are not because Apple is stupid, it's because Apple wants to differentiate itself from everybody (Cmd+down to open, Enter to rename, Sort folders with the rest of the files, Play/pause key starts iTunes even if you are in another music app, the piece of shit that is Mission Control as the only way to manage your open windows, the crap fest that is the Dock and the fact that you can't see all open documents, just the open apps - unfortunately it spreads like the plague to other OSes and I could go on for a long, long time).
Heck, why would you do a clean install in the first place?
Oh, I don't know, maybe the fact that it took 5 minutes to start the computer. Possible fragmentation issues, I don't know since there is no defrag tool included with the OS, and defrag programs cost a lot of money for the Mac.
