Just when the democrats seem to have all the momentum, they bring out the Blago and Burris show. Probably not what Obama had in mind. As a Mac user, I’ve enjoyed watching Apple build its momentum against the seemingly un-seatable Microsoft. And I’d say 2008 was probably the momentum shift year where Mac sales increases outpaced PC sales increases by a 2-1 margin and the iPhone and iTunes were clear front runners in advanced media and mobility. Just when this momentum seems like it’s peaking, Apple announces the end of showing at Macworld. This in my opinion is a huge mistake. Somewhere, somebody ran numbers on the cost of doing the Macworld expo and probably did a linear computation related to sales. But the longtail of a single keynote is just that. People remember the iPhone announcement in 2007 and that wonder still permeats Apple stores that attract 3 million people per week. The ads are great, but they are just ads. Real people giving real presentations leave a lasting impression that Apple will need to find a way to make up for to keep the momentum going.
