We need to use a specific version of NaCl SDK for each Chrome version. See http://http://code.google.com/chrome/nativeclient/docs/runni...
Knowing how quickly the Chrome version changes and automatically most of the times, it will be very difficult to keep up.
Also please make it clear with a badge or something on the home page that you can ship only to US currently.
It is not clear until user clicks a (small) 'details' link on the "Your Order details" step.
Can't order as a non-US but some suggestions.
Please check the default options so user can go through first step in one click.
IMO Small margin, White background can be the default options.
Great idea though. Looking forward for other products.
Nice layout. I do want to point out a lot of text on the home page are images. "Join Buddify" "See 5 great reasons ..." "Cool people on ....". They can be replaced with texts and themed with CSS
