Basically the bug is in regards to the cache memory I believe which when disabled, has the processor running at a perceived slower speed - no cache slower reads/writes from external memory. In one of the threads there are some links to Intel\'s site regarding the cache bug (#100 if I remember correctly). I purchased my Zaurus from Amazon and was a bit bummed when I got the 250 processor but now its a dont care. The device works as expected and all of my CF accessories are working the way I want them to. As a general engineering tool, the Zaurus should be quite nice. A lot more flexibility then the other PDA\'s out there. The down side is that you have to be willing to experiment and do some research in order to get some things to work. For the most part, standard accessories will work fine, if however you have something that is new then there may not be a driver available for it. Of course the same problem exists with other PDA\'s also - case in point, CF drivers for my Clie.
