I think it's for a certain kind of workflow. If you want to watch YouTube videos it kind of does nothing useful. If you want to swap between documents and reference materials a lot, much more helpful. I think the answer is "It sucks because it's for multitasking, not because it is a bad idea."
I think it depends less on workflow and more on screen layout. If you run your browser maximized on a landscape-mode display, there's a lot of horizontal real estate that isn't very well-used, while vertical space is at a premium. So it makes sense to move tabs to the side.
On the other hand, if you don't maximize your window but keep it as narrow as possible (so you can see other windows) but just wide enough that sites render well, then you'll probably prefer them on top.
On the gripping hand, if you're like me and run your browser full-screen on a portrait mode screen, then you have gobs of vertical real-estate and tabs on top definitely makes sense.
(I have three monitors, a 32" (landscape) in the center, which is where my IDE, editors, and "focused" work lives, and a 27" portrait orientation monitor on each side. The left one has a full-screen browser window for work stuff and the right one has a full-screen browser window for personal stuff. It's fantastic.)
