The XPS M1530 is the 15.4" brother of the 13.3" XPS M1330 and seems to be about 50EUR more expensive than a similary-configured M1330. The M1530 base configuration is priced at 849EUR in Belgium (excl. shipping and VAT) and the notebook weighs only 1.98kg (4.37 pound). According to the ad the XPS M1530 has a battery life of 8.7 hours but that seems over-optimistic.
