Increased market share can only be a good thing.
Most people I know however, who were using macs at uni or at work, have all switched back to windows in the last year or so and they are not looking back. I suppose marketshare in the UK is not in par with the US. It would be interesting to do a survey of this increased user base and discover the role of the mac platform as it has evolved these days.
I suppose my question is: Has the mac/osx platform changed direction towards its function and purpose? What is a mac with osx good for these days?
A few years back the mac was the platform of choice for the creative class such as designers, photographers, Video editors, etc. Most of these people, with the exception of video editors, have now switched to windows because of the better choice of software and better upgradeability.
