in case anybody reads down this far,
Opera mini is pretty good. The UI for tabbed browsing as well as for the "back button" feature is impressive.
As for font rendering, it doesn't waste tiem and processing power "re-rendering" the font every time you zoom ever so slightly.
Opera handles large pages or graphically intense pages very well, and is FAR faster on my regular 3G iPhone than Safari is.
In short, they fix zoom (which is rather fine for me, tbh, but i'm young w/ young eyes) and I'd say it's far sexier than Safari.
