Yeah, the 133MHz CPU just isn't going to be fast enough for my needs, plus
the extra ports is a bit over kill for this specific application. I know
the gumstix is a higher price, but it is exactly what I needed. Thanks for
the feedback though. All this neat hardware that people are sharing is
giving me ideas for future projects.
