Side note that just occurs to me due to another thread that just started.
All 5600 are NOT created equal. It was originaly released with a pxa250 xscale, which had a serious design flaw, making it slower that the old 5500. Very bad. This was Intel\'s fault, not Sharp\'s.
Anyway, Almost a year ago now, Intel stopped all production sand sales of the pxa250 processor, in favor of the pxa255, which has been upgraded since. (I believe the mythical 6000, should it ever come out, is supposed to have a pxa 263 or some such thing)
Anyway, many of the new sl-5600 have been upgraded (without a word at all from sharp) to the pxa255 which is about twice as fast in terms of actual performance.
So, you want to look for one of 2 things, either a PXA-255 X-scale,
OR
A an X-scale with \'C-1\' stepping.
