I really don't agree with the author's complain. Particularly the download window. I HATE when a new window popup when a download start when I use firefox. The chrome's way is so much better; you can easilly see the progress, click on it to open and even drag it. If you don't want to see that, you just close that bottom dialog. In fact, I really rarely use the download tab; only when I'm searching something I've downloaded.

I have to agree about the developer tools though, it's really not as polished as the rest. Probably because only developers use it and they don't mind as much? Or the product manager doesn't use it? I can't say.
