The detectionofcorrelate peakis one of bottlenecks ofoptical signal processing in LPI radar. We devised thesmartpixelsandRAMcamera to solvethisproblem.
The major differences you'll want to consider (aside from design) are the larger size, and the fact that the 14z makes room for an optical drive and up to 8GB of RAM.
Additionally, upgraded machines tended not to be good values, as boosting the RAM, hard drive capacity, and optical drive drove the price "beyond the reach" of most business laptop customers.
