As someone who has upgraded every single version of every single OS he has ever known on the day and date of its release, I've been watching the consternation surrounding the retirement of Windows XP with some bemusement.
To me, tech is all about progress and moving forward, not about clinging desperately to workflows just because they were the first you learned or the ones with which you're comfortable. But, having hung around the Amiga diehard community for decades, I don't doubt that there will be XP machines in use long into the future.
Coincidentally, new Surface Pro 2 user and professional artist Mike Moreu sent me the comic below last night. I think it does a great job summing up the lengths to which some enthusiasts will go to preserve their preferred operating systems. Enjoy!
