Teehan + Lax is an interactive design agency that does work for multinational corporations. Their site is obviously catered towards clients with big wallets or potential hires. Complaining about bandwidth would make a lot of sense if we were talking about a site catered towards the majority of internet users, like an Amazon, Craigslist, or Reddit. It's like complaining that high end fashion websites don't cater to Internet Explorer 7 when a far greater majority of their users uses view it through iPads or mobile phones.
Actually, I opened it in Chrome on my SGS3 and experienced no problems at all. The page was snappy and responsive to things like scroll, and it loaded quickly. I actually didn't realize there was any problem at all until I read these comments.
I viewed the site on in Chrome on a rMBP and it looked and loaded just as poorly. There's no excuse for having basic fallbacks or a preloading mechanism.
