I would like a ThunderBolt ( Apple is the first to introduce = it so I will give them credit even if Intel is the creator ) logic analyer = and digital scope peripheral. Transferring data at high speed is very nice= .. The peripheral can handle triggering and data collection. The laptop ca= n be used as a display or to do spectrum analysis or ..... I can think of other embedded peripherals that USB 2.0 just doesn't cut it.= Analyzing 4D data from multiple cameras ...... you can never be too hands= ome and external data transfer can never be too fast. gus in denver 99gus --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
