As demonstrated during today’s keynote, Connectix has released VirtualPC for Mac OS X Test Drive, a public preview of the company’s PC emulation software. Servers are currently flooded with requests, however, so gaining access to the download may be difficult. Connectix has also posted DoubleTalk 1.1, an update to its network utility that allows Macs to access Windows networks. The new version adds Network Browser support, a printer setup assistant, alias support, and more.
