MAC:

Owners still claim boasting rights on the grounds of elegance and reduced vulnerability, but it’s doubtful whether the benefits really do outweigh the costs and disadvantages. I guess it depends what your priorities for use are.

LINUX:

A wonderful project that has survived far beyond the sneers of the doubters. Fun to use if you’re a tad on the geeky side and don’t expect it to solve your every wish. It’s hard to see it ever seriously challenging Windows head to head, but we can but hope.

WINDOWS:

Still the only game in town for the serious games nut. Microsoft has been applauded for its part in bringing much needed unity to the chaotic early computing scene, but seems to be widely loathed for its monopolistic attitudes.
