Hewlett-Packard Tuesday launched a new line of low-cost business notebooks called the ProBook s-series that merge business functionality with consumer goodies like HD graphics and Blu-ray drives. The HP ProBooks give you a choice of an Intel or AMD processor across most of the line, as well as choices of 14-, 15.6-, or 17.3-inch diagonal HD widescreens with a 16:9 aspect ratio.

Models come in glossy noir (black) or merlot, though merlot is only available on the 14- and 15-inch models and is not expected to be available until June.

HP is offering two OS flavors: Windows Vista with available XP downgrade or Novell's newly released SuSE Linux Enterprise Desktop 11. The ProBook series also has a few HP specialties including the HP SpareKey button which lets you answer three personal identification questions in case you forget your system password; one-touch access to e-mail, calendar, and contacts with QuickLook 2; and the File Sanitizer utility that can completely wipe individual files, folders and personally identifying information from your hard drive.

The ProBook series starts at $529 MSRP.
