    How much speed difference is there?
    Battery I take it is almost double in real life, actually using the MBA. I get barely 3 hours with moderate use on my Rev B and I take it most people get close to 7 with similar usage?

    I went from a Rev B 1.86GHz SSD to a Rev D 2.13GHz SSD with 4GB RAM. The difference is night and day. The Rev D is significantly faster on virtualization (the most processor-intensive task I can give it). Although the processor speeds are identical to what was offered on the Rev B and Rev C models, the Rev D has better heat management, so it doesn't throttle down as much.

    The SSD is also about 4 times as fast on the xBench tests, which translates into faster application start times and disk tasks.

    Factor in the extra USB port, the faster GPU, higher resolution, and additional RAM and storage options, the Rev D is a significant improvement.
