   It does use classes... it's all the slightly different <span>s with 
classes and inline styles (25400+)... removing the <script> .. 
</script>s and the obvious duplicate styles only saves about 100k... it 
renders in ~2 secs or so and the layout is correct but the fonts are 
borked... for some reason the @font classes aren't getting transfered... 
hmmm, thought I was on to something there for a moment. Btw, it did 
render nicely on my Android phone... only the context menu didn't work.
