I didn't notice the lack of a status bar - that's always been one of my biggest beefs about window design. I require the information that's in the sidebar, but why have those 20 pixels constantly taking up my browsing space? Google's implementation is extremely fluid, I love it.
On the other hand, I'm getting random timeouts that appear to be of a DNS nature (Firefox has way, way, way better error messages - I'm surprised that Chrome's are so IE6-esque) when I have had no problems with other browsers. A couple refreshes fix it, but it seems odd.
