    The guy make a real world benchmark and conclude that a 1 GHZ TM5800
    with latest CMS and PTT should be comparable with 1 GHZ PIIIm.
    Normally TM5800 users will say it is comparable to 600-900 MHz PIII.

    About running Linux on it. Application launch time is not good
    (18 sec. to launch GNOME Help, 7 sec. to relaunch). But after that
    it seems like linux GUI apps are more responsive.
    Building software projects seem to take longer than it should be.
    Building take more than 4 days while it take
    about 1-2 days on PIII. I guess the CMS has to translate 'gcc'
    on every invokation? If so, can the kernel help in any way?

    Battery life and Linux should be Ok. You'll have 'longrun' utility
    to control cpu power consumption vs. performance. I understand
    that the CPU already control its power consumption itself, even
    without the help of the kernel, right?
