A couple things I've already noticed that I'm a little dissappointed with: There doesn't seem to be an automatic spell check like Mozilla has, and the zoom feature is only a text size changer, not a natural zoom like Opera or the latest Mozilla. Perhaps they are still working on that.
Despite being currently beta, as are so many of Goggle's applications, it's pretty fair to say that it's still better than many other applications. Being open source, it will be fun to see all the projects that spin off from the various pieces that make up this new browser.
I'm definately going to give Chrome a whirl and see how my web experience changes. And of course, now I need to test all my web applications to see if they behave!
