Dell’s high-end laptop lineup just picked up a new brother — the XPS M1530, a 15.4-inch notebook complete with webcam, fingerprint reader and touch-sensitive multi-media buttons, not to mention the stylish design found in Dell’s previously released M1330 13.3-inch notebook. While the M1530 is certainly larger than the M1330, it’s not exactly a heavyweight at a mere 5.78 pounds.
