I absolutely hated Unity to the point of writing some slightly heated stuff on the Ubuntu message boards on the net.
I have to admit that although I am, and was right about Unity not being very user friendly, I do see the Ubuntu team(s) working to make it better though, and hopefully they have heard our voices.
The main pet peave for me is that the min max and close buttons belong on the right, and in that order, and should be an option (without going into gconf-editor) for the end user immediately, if not the default setting.
The world is used to and likes those buttons where I mentioned they should be, and shouldn't have to change because someone on one of the Ubuntu team(s) or someone at Canonical thinks that's the way it should be.
Just my rant on an otherwise beautiful operating system. I still love Ubuntu,
I just want Unity developers to keep in mind that Unity should fit the user, not the user fitting Unity, which is ridiculous.
