The question is - can you live completely without Windows, or do you sooner or later have to resort to Windows again?
There are three reasons why you might wish to keep Windoze around.
1. You might wish to run programs for which there is no Linux equivalent.
2. Some websites provide services that require a Windoze environment.
3. If you have a hardware problem, being able to reproduce it on Windoze may be necessary to get the vendor's attention.
