There are functional and ergonomic reasons to move the taskbar. IMO the most useful taskbar position is at the top because everything we do happens on the top 1/3rd of the screen. File menus bookmarks, address bar, minimize, x-out, browser navigation, on and on I can go. However, if I want to interact with the OS I have to drag my mouse all the way down to the bottom. If I want to check what app are open, see the time, date, widget info, I have to look at the complete opposite side of the monitor that I spend 80% of my day looking at.
In a 16:9 the majority of the screen real estate exists on the sides. Makes sense but I don't care but the bottom is the stupidest of all places for the taskbar to be located. Microsoft only put it at the bottom to make it different from Apple and Unix so they could file copyright. Just ask Bill.
Please for us efficiency freaks, let us move it to the top!
