Do you not get output like the screenshots ?
Again, if all the text I look at during a session at the computer were rendered by Plan 9, I could probably get used to it (since I ran Linux in text mode for years, and the text mode on my video card had no smoothing unless I am very, very much mistaken), but that would be impractical because Plan 9 does not have a satisfactory graphical web browser. You're not going to contest that last statement, are you? Heck, even Russ Cox does not use Plan 9 for browsing the web.
Plan9 has three graphical web browsers but no, not CSS3 & JS. Russ doesn't even run a Plan9 terminal at all so he's not much of a benchmark.
If web browsing is what you use your computer for, then perhaps Plan9 is not for you.
Plan9 doesn't have anti-aliased fonts by default as it uses bitmap fonts. There are unofficial builds that use TTF fonts (I run one of those) and also some other NDA goodies. I think perhaps the TTF will migrate back into the main.
