For those not up on computer history, Osborne was a computer maker that announced a great new model coming in a year... so sales started tanking while people waited... which meant there was no model in a year (or maybe there was, my memory is fuzzy on that detail).
Microsoft had a pattern of doing this throughout the 90's, and it generally worked out well for them. As soon as other PC operating systems (and OS/2 in particular) started chipping away at the badly aging Windows 3.1x line, Microsoft started promising the moon with Windows 95/PC DOS 7 -- more than two years before it shipped. They didn't deliver on most of their promises, and the end result was worse than the competition, but by that point it didn't matter -- people believed the hype and decided to skip the competition out of fear that the competition was going to be eclipsed in a years time. They did the same with Windows NT. Remember "Cairo"? Microsoft started talking about it in 1991, and continued through 1996 before dropping the release completely. WinFS probably takes the cake -- a complete redesign of how a PC OS stores information, it was first promised in 1991, and was continually touted until 2006, usually in around whenever a competing OS was being released.
Over-promising way in advance and under-delivering was MS's modus operandi through much of the 1990's and early 2000's. A lot of people fell for it, and a lot of people continue to fall for it (I follow some PlayStation forums now and then, and have seen more than one person claim they're waiting until Scorpio ships because it's going to blow everything that ever came before it out of the water...sound familiar?).
