Chrome is nice and fast but lacks a lot of funcionality in most sites i am member. For example, a few "blog" sites will not show me the toolbars i need to edit my posts and blogs. I do like the fact that if one browserwindow crashes the other windows are not affected by it.
Currently i use chrome for sites that i don't need and adressbar for (like my chatbox on my forum) and that i want to have quick access too, the shortcut option it provides is a very great tool for this
i love chrome, i use firefox for when i need to use a extension, but chrome almost never crashes and i was using FF 3 and it would keep getting up into the 300K memory use with only 2 tabs (facebook, x10) but when im using chrome its at like 75K
