It's not necessarily all about speed (or what theorists would refer to as single-task completion). It's also about increasing throughput.

Google adds a pinch of concurrency to its web browser (each tab running in another thread) and it improves the client side experience.

I don't think throughput is a barrier at the moment.

The main touted benefit I've heard of Chromium's tab-threading is insulation, so if one tab crashes it doesn't bring the whole browser down.

Actually, I'd say the main benefit is that closing tabs actually releases memory because those processes die.

New computers are coming with gigabytes of ram, I have 2. On the other hand, I rather enjoyed watching a quicktime crash take down only 1 tab. I kept loading it repeatedly.

[gnaritas]

I have 4, that means nothing when the browser keeps bloating up and taking gigs itself because opening and closing lots of tabs all day long fragments the memory so badly that it can't release ram back to the OS when you close some tabs.

In Chrome each tab is a separate process, which is mostly for stability (if one crashes it doesn't take down the whole browser).
