I haven't read that article, but I will chime in nonetheless
Edit: I have just read the article. That guy is a moron. Maybe I'm just clever, and able to tell my icons apart without needing the labels?
The dock is gorgeous, and functional. However...
My first computer with a GUI was a Mac. An LC475 (if memory serves...), and it was great. I loved it. I had used Windows 3.11 at work, but to me that was just a DOS program.
Then in '96, I got a new job, and had to use Windows 95 (within a few months, I was able to switch to Windows NT 4, then 2000 and then XP, so I was never subject to the awful Win95, 98, ME issues). The first thing I did was move the task bar to the top of the screen, and the Recycle Bin to the bottom right, to replicate my Mac desktop as much as possible. This made a lot of sense to me, because all programs and windows have their controls and menus at the top of the screen. So it made sense to have the task bar up there as well. I continued this way until I switched back to Mac 1 month ago.
I have to say, now that all my stuff is at the bottom of the screen in the Dock, it does feel somewhat counter intuitive. I also find myself using Command+Tab a lot more than I used Alt+Tab on Windows (and no, I never used apps full screen on windows).
In those Mac-less years, I never had a problem with Windows. It's a fast, efficient OS that never gets in the way of what I do (Web Design). So, why did I switch? Cool hardware of course. Nothing beats Apple. As long as I have Photoshop, who cares what it's running on.
