Just last night, our own Dear Leader was on the radio talking about Microsoft’s latest salvo in the browser wars. This morning, the battlefield has changed completely, thanks to the surprise arrival of Google Chrome.

To be precise, Chrome isn’t here quite yet: the beta is due out later today. For now, I’ve had to content myself with reading the product notes, which Google has oddly elected to release in cartoon form. Cute, but hardly practical.

Still, it looks like a lot of good ideas have gone into Chrome, and there’s one idea that excites me in particular:

As I say, we’re still waiting for the beta, so we don’t yet know how this works in practice. But running each tab, and each extension, as an independent process should, in theory, enable Chrome to make very effective use of multiple CPU cores.

Thus, not only is Google set to shake up the browser wars; it could actually make “cloud” computing as stable, efficient and responsive as local software – or more so in many scenarios. That would set the scene for a revolution in our very model of personal computing.

Of course, for now this is all just speculation. But even without seeing the software, I can confidently say this much: Google hasn’t lost its knack for disrupting the market.
