Hey, I appreciate your thoughts.
Now, to "defend" myself...
I'm afraid that using a regular table wouldn't allowed me to create this pricing table as it looks now. Although this is called a "pricing table", I think using a table isn't recommended in this case as it is quite restrictive.
Also, I avoided using HTML5 elements like "header" because I didn't wanted to include an extra HTML5 shim (for older browsers) dependency.
Regarding using <b> versus <strong>, this could be a long discussion here :). I think <b> just fits in this case as I don't want to add any importance from a content or SEO perspective.
