The next step for the safety board will occur on Tuesday in Tucson, Arizona, where the battery charger and power starterunit will be tested and relevant data downloaded.
While you could probably get along without WiFi in a home-based console that already has Ethernet, and you can always presumably hook up a memory card reader via one of the unit's four USB ports, the lack of HDMI output makes this pretty much a non-starter for anyone hoping to actually use the PS3's Blu-ray drive for anything more than playing games.
