[Coda]

The layout is fairly taxing on Internet Explorer. Every other major browser -- Safari, Chrome, Firefox, Opera -- and actually many lesser-name browsers (Arora, Konqueror, Kazehakase, Galeon, Epiphany, to name a few) can handle the layout just fine at full speed. The IE9 betas, from what I hear, do a pretty good job too.

Internet Explorer 7 and 8 should at least WORK -- I test the layout in them both on my own Windows box -- but I'm well aware that they could be slow. If the shops are particularly bad I'll see what I can do to speed them up.
