These benchmarks provide interesting discussion, but they are a very poor tool to help your average-to-semi-saavy user choose a model based on performance.
The vast majority of computer usage is a mixed bag. The "feeling" of speed is derived from subjective things such as how long a web page loads, how fast apps launch, boot times, etc. The SSD drive is the single biggest improvement in most of these instances, probably more so than even a jump between CPU generations (i.e. Core 2 to Core i). Whether or not it takes 6 minutes or 6 minutes and 30 seconds to render something in iMovie is really irrelevant to most users, which is what these benchmarks will provide better comparison for than the 'real world' usage.
