So far the browser is pretty good in my opinion. I haven't had to download any plugins, I haven't had any real hassles, and I like some of the features that even Firefox lacks (like the ability to control tabs and memory management, changing a tab into a window, etc.) What I'm not liking is the look of the browser... it looks like a Fisher Price deal. Even the logo is kind of kid-like, but maybe that was the look that they were going for. I like how the address bar only highlights the domain and for the most part, only goes to the domain when you begin typing in the address of a website. (Firefox remembers names of websites so that's not all that new.) Sites show up fine and not garbled (so far) or out of place. I feel like I'm running this fullscreen all the time... Chrome is invisible as a browser by default, maximizing viewing space. The options are rather limiting though... which is a good and bad thing, considering there's less to tweak and consequently, less to mess up.
Basically, it reminds me of Firefox (since it kind of is like Firefox) but with some better features. Not bad for beta at this point in time.
Can't wait for skins, at the very least. So far, I'm still using Chrome at work, so I guess that says something in itself.

Won't use it at home until RC, though.
