Windows 7's "XP Mode" Won't Run on Some CPUs (PC World)

PC World - Hoping to use Windows 7's XP Mode on your new laptop? Better check your specs, because many big-name, Intel-powered notebooks including Asus, Dell Studio, HP Pavilion, Sony Vaio, and Toshiba Satellite models may not have what it takes to run Windows 7's XP mode. Featured in the recent Windows 7 release candidate, XP mode allows XP-specific applications to run inside Professional, Ultimate and Enterprise versions of Windows 7.  Microsoft included XP mode to entice business customers to upgrade to Windows 7 even if they're using custom-made programs that run only on XP.
