The poll could have used a few more choices. I went with 'Other'.
My view is that 'Personal Computers' are meant to be, and in the 21st century should be appliances. Something for the masses.
Though a computer, something more like a 'Workstation' is something aimed at the developers, be it applications, CAD/CAM industrial uses, or professional content creation. After all, somebody has to design and build the Personal Computer, the applications, and the content consumed by the masses.
In reality, most computers (Workstations) outside the corporate landscape, spend a majority of their time performing Personal Computer tasks.
