Dell XPS 15 L502X: An Affordable Multimedia Marvel | PCWorld
Dell, as usual, offers a slew of upgrade options--including faster CPUs, more system RAM, and GPUs with more memory--that can dramatically increase the price. Other components that are upgrade candidates include the 500GB, 7200-rpm SATA hard drive (you can opt for a 256GB solid-state drive); the 8X DVD burner (you can pay extra for a Blu-ray drive); the 56-watt, 6-cell lithium-ion battery; the keyboard (you can get a backlit one); and the Intel Centrino-based 802.11n, 2.4GHz Wi-Fi (upgrade options include dual-band 802.11n Wi-Fi
, Bluetooth, and WiMax). It's disappointing that the basic model doesn't include Bluetooth.
