Who said anything about pitifully outdated processors. I can buy a heck of alot of CPU horsepower w/out buying the latest/greatest CPU. As a matter of fact, in almost all cases, the best bang for the buck would be for processorts that you imply to 'pitfully outdated'. > Embedded MBs with speeds enough to eliminate the requirement for 1) a > slot and 2) an external board are available for less than the delta in > cost. That's simply not true. If you are building 'truly embedded' systems (ie; 100K+ boxes), you're not going to be using 'off the shelf' PC parts. You're going to be specifying particular parts to be used, and in general the difference in cost of $1-5 for the CPU makes a *huge* difference in the price-point you are trying to make. Often times it's easier to build a hierarchy of products, with each individual tier having the same 'basic' setup (keeping costs low), and by adding additional 'special purpose' boards, you can increase the functionality of the box by only increasing the costs trivially. > So, logically speaking, anyone > with a requirement for crypto would simply chose a faster embedded MB > solution. You seem to have a different definition of embedded than many others do Bryan. Have you ever been involved with specifying and building embedded systems products, or are you just talking out of the side of your mouth?
