> The most logical tab position is on the left or right, on desktop, because most of the space on a wide screen display is on the horrizontal axis, and you want to reserve as much vertical space as possible for scrolling websites (which happens vertically, and pretty much cannot be changed at this point, as it is baked into the web).

This assumes a landscape-oriented monitor.

I would suggest trying this out on a portait oriented monitor. Tabs on top make the most sense there.

Also, I would generally suggest trying out a portrait oriented monitor. It's quite useful for coding, reading, etc.
