I wonder if it is possible to pin the Mac OS X Dock to the top in Snow Leopard? I see lets of ideas on how to do this when I google for it, and Secrets (the tweaking app) also provide it as an option, but I don't see any of the ways working for me.

I guess it must have worked at some point, since people said it did, but I believe this feature might have been removed from Snow Leopard, and therefore does not work for me.

Is this so? Is there really no way to pin the Dock to the top of screen?

If not, what ways of "getting rid of the dock" can you guys recommend? I have tried with auto-hiding, but my problem is that this will leave a 4px line at the edge of where the Dock is pinned to, that applications wont cover. Thats not ideal for me. As far as I have understood from googling, this line will not appear if the Dock is pinned to the top, hence my question.

What other ways do you guys use to get rid of it?
