I'll probably get modded down for this, but here goes...
People are trying hard to hang on to their old Win95 style workflow. Nothing wrong with that; however, for me, the old workflow with the start button and horizontal panels at the top and bottom of the screen worked better on the older 4:3 monitors. With today's 16:9 flat-panel displays being ubiquitous, having panels taking up vertical real-estate doesn't seem like such a great idea.
I personally like the way Unity and Gnome-Shell are doing things. Since today's flat panels have more horizontal real-estate, I'd prefer a DE that makes better use of it. This is what the panel in Unity and Gnome-Shell do. They get rid of the old top/bottom horizontal panel, and replace it with a vertical panel on the left. Sure, it can mess up people's work-flow, especially if they are used to the top/bottom panels from Gnome2, as I was; however, after using Gnome-Shell for a few months, I've re-worked my workflow, and actually feel more comfortable with the additional screen real estate afforded by ditching the old panels. Sure there are still issues. But I think people should try it out for themselves before complaining. Of course, it would have been nice for Gnome-Shell to at least give the option to users of having the old panel, even though, I now would never use such an option.
