There are a few things keeping me from Chrome as well.
- Firebug. The dev tools for chrome are nowhere near as good - the features that I use anyway.
- It's really a nit, but I cannot stand applications that don't at least look like they're using the standard window decorations. I want it to match the rest of my OSX, Windows, KDE, Gnome apps, whether it's skinned qt or gtk, I don't care, but it needs to look like it's supposed to be there.
- I'm used to Firefox. On my mb pro, there is no noticeable difference in performance between Chrome and FF.
If Chrome at least had good enough developer tools, I'd be willing to give it more of a shot and see if I get used to it, but for now, it just gets in the way.
