Not all Chrome's features are new - Firefox and IE8 share some if not most of them.
For now it is quite harmless, but when armed with a future Google minimalist OS, and over Google minimalist window manager, will bring end to end autonomy to Google. Can't it be possible that nobody cares about being totally controlled by Google?
Now I'm beginning to understand those conspiracy theory lunatics warning us about aliens and underground politics ...
My current experience: IE8 is now the browser that uses less memory. Followed by Chrome (it problably didn't have a chance to make use of it tab memory management features). Firefox3 is absolutely disastrous - please note, I'm loading 7 or 8 add-ins. Some thing with startup time.
