Microsoft talked hardware during its address at the Computex 2012 trade show in Taiwan this week, and while most people have been focusing on the future—with Windows 8 and a coming generation of hybrid PCs, tablet PCs, and other non-traditional computing devices—the software giant also took a step back to remind people about how much PCs have evolved over the past year. The resulting promo video, shown here, highlights the evolution of the PC over just three short years.

Interesting stuff. I bet a similar video three years from now will be even more dramatic.
