Writing at LaptopMag, Mark Spoonauer offers the following list, which I've summarized here along with some additional commentary.
10. “There’s no chance that the iPhone is going to get any significant market share.” --Steve Ballmer, Microsoft CEO (April 2007). Talk about a patient board of directors. Under Ballmer's stewardship, MSFT appears to have whiffed on every significant consumer technology trend over the last 10 or 15 years.
9. “There is no reason anyone would want a computer in their home.” --Ken Olson, president Digital Equipment Corp (1977). Not long after, DEC was toast, forced into a merger with Compaq to survive.
8. “We’re going to become better than No. 1 (in tablets).” --Eric Cador, senior VP, Hewlett Packard (2010).
7. “Within the next two decades autos will be made with folding wings.” --Eddie Rickenbacker, pilot (1924). Rickenbacker, the famed World War I ace, might have been off by a century or so.
6. “Cellular phones will absolutely not replace local wire systems.” --Marty Cooper, inventor (1981).
5. “In five years I don't think there'll be a reason to have a tablet anymore.” --Thorsten Heins, BlackBerry CEO (2013). Well, he could be right. He still has 'til 2018 to be proven right.
4. “The subscription model of buying music is bankrupt.” --Steve Jobs (2003). At least Jobs course-corrected quickly.
3. "Remote shopping, while entirely feasible, will flop.” --Time Magazine (1966).
2. "Windows Phone will be No. 2 in Smartphones by 2015" --IDC, Gartner, IHS. Well, two years to go.
1. “I predict the Internet in 1996 [will] catastrophically collapse.” --Robert Metcalfe (1995). Metcalfe, one of the inventors of the Internet, appears to have underestimated his own child.
