Comparison chart usability can be improved by organizing data such that the chart merely indicates feature availability - yes or no. Since, this is just binary information you can also avoid actually using the words "Yes" and "No" and replace that with a visual cue such as a tick mark or some graphic. The less the user has to read, the better. Further improvement is achieved by ordering the features so that all available (or unavailable) features are close together.

Here is an example of a much better chart - the MSDN subscription overview.
