Chrome is fine for some applications. Firefox's add-on infrastructure and better memory management with large numbers of tabs make it the superior browser for my needs.
I like to use Chrome on Virus-infected systems so that I can otherwise uninstall outdated Adobe shit, since it has its own built-in Flash libraries and PDF reader. I used to think that it worked better for older computers, but it has become at least as heavyweight as Firefox over the course of the last year that it just just as utterly unusable as every other modern browser on old hardware.
