The only thing crappy is you, you'd you rather pay $200 for a "non-crappy" OS that runs authentication checks on you every so often and requires the use/payment of an Anti virus program, when a free OS such as Ubuntu can do ALMOST everything the same that the non-crappy OS can do and does not run auth. checks or force you into the monopoly of purchasing anti virus? That crappy OS (not ubuntu but Linux itself) is used by the astronauts in the International Space Station. It also powers Amazon, Twitter, Facebook...oh and you'd never guess, the Blockland website/master server. It's also used by Disney and Pixar to render things that were made in Maya/3DSMax such as the movie Shrek. So, before you come and tell someone an OS is crappy, look it up first.
How does windows force you to buy av software. Hint: It doesn't!
Also, linux might be extremely good for render farms or servers due to being lightweight, but that does
not make it a good OS for a home computer.
