I just went and changed my theme to something less busy because the one I'd been using over the past few years (Beach) was way too distracting in the new format. Otherwise I think it'll be okay. One downside is that my work makes me use IE and they haven't upgraded to a compatible format to the new gmail, so I'm stuck with the original basic html version at work. Not too concerned since I only have five more days left, hopefully they'll upgrade IE before I'm back in 2013.
