Todays computers are available in a vast array of speeds, shapes and sizes, from the smallest budget models for basic internet and office use, to high powered 3d modelling workstations and everything inbetween. The diversity ranges from small hand held tablet devices that can be used anywhere to large desktops that could render 3D animations for Pixars latest film.
