I prefer to use gmail in standard mode when possible. I switch to html mode when I'm desperate (which happens when standard mode becomes unusable due to bad internet connection). Opera/OS2007 works fine for this. If it doesn't with MicroB in OS2008 then that's a major concern for me. (It's a bit strange to hear this, because if I'm not mistaken there was a recent post claiming the opposite: That gmail worked faster and better in OS2008). Well, it's a beta.
