How can you tell when a vendor doesn't have to care about their customers? When they do things the Comcast way:

Last month Dave Winer noted that Comcast's installation procedures require the use of Internet Explorer. Another Comcast user makes the same complaint. "They helpfully provide you with a CD that has a custom Comcast-branded version of IE5 for the Mac, because Apple hasn't shipped a Mac in quite a few years that has IE5 on it by default."

Even Comcast's web page shows an apparent bias against Mac users — or anyone not using Internet Explorer. When you click the page's "Games" hyperlink, an error message pops up, warning that the site "is not optimized for Firefox browsers or Macs."

If they had to compete for customers, instead of being the only (or, at worst, one of two) choice, would they act this way? I really doubt it
