Gateway (the Acer of American PC vendors.)<p>HD DVD (acronym overload, no differentiation from Blu-Ray.)<p>Vonage (like Skype, but with an AT&T syntax)<p>Youtube (low definition format, low comment intelligence, low interest cellphone videos.)<p>Sirius XM (financiers of Howard Stern lost to the Chinese $5 FM transmitter makers.)<p>Microsoft Zune (the portable version of Windows Media Player but only browner.)<p>Palm (HTML5 based "OS" might help you now, but I will never forgive you for that Pilot API.)<p>Iridium (never heard of them before Miami Vice, the movie, and never since. Lost to regional sat services)<p>Segway (a wheel-chair for the able-bodied; early adopters considerably dorkier than rest of population. Way too much of a "tourism office" gimmick toy than anything nowadays.)
