what about text as images?
It's currently Chrome-only unfortunately.
edit: ...and Kerning, text-flow, font-weight, character maps and other gripes.
Also these images look like they used gray scale instead of sub-pixel rendering so the differences in pixel geometry should be more or less mitigated.
I'm sure in theory it could look better as actual text for certain setups, but this probably allows them to get the best looking text in the widest amount of configurations.
I tend to use text as images for logo fonts and banner fonts where you want to ensure the client doesn't render it in some weird way.
