    Ha, yeah I was just going to say "think embedded". ABP is a much
    simpler spec and programming interface than HPET, and since we were
    designing new custom silicon, it made sense to just do the simple
    thing, rather than butchering an existing spec, then making a partial
    HPET that looks like ABP anyway and forcing any future HPET updates to
    conform to the new standard (very similar reasoning to the ACPI vs SFI
    discussion btw). Hopefully the technologies we've come up with for
    MRST will be flexible enough to be used in future platforms as well;
    we'll see.
