Skype and Dell agreed today to ship Skype’s video Internet calling software as an option to Dell’s new XPS mobile systems, the XPS M1210 and XPS M2010. Under the terms of the agreement, Dell will offer to pre-load Skype on the XPS 1210 and 2010 as part of an optional audio-video communications package that also includes an integrated rotating webcam, noise-isolation earbuds and mobile broadband capability. The move comes just after Dell agreed on Thursday to pre-install Google’s search application for scouring a computer hard drive and emails, and a Web browser toolbar linking to Google’s online search engine and other services.
