MacBook Air benchmarks posted

Macrumors has recently tested both default configurations of the MacBook Air; the 1.6GHz HDD, and the 1.8 GHz SSD. How do they measure up to more conventional Apple portables?
Macrumors achieved the following using XBench:

Immediately, our interest gravitates toward the performance gain brought by the 1.8" SSD found in the high-end model. The performance gains correspond with what one would expect when comparing solid-state flash memory to a conventional 4200 RPM hard disk. The SSD is incomparibly faster in all but a couple tests, where the conventional hard disk pulls away in sequential writes, which has always been a weak point for NAND flash memory. Looking at the rest of the results, the MacBook Air seems to be very slow compared to even a regular MacBook. However, intended as a satellite machine, the MacBook Air's power-to-size ratio, along with software features such as remote disk and wireless Time Machine backup, make it seem a logical choice for those of us with more than one Mac.
