Let's see, now.... So you enjoy BUGS, do you? Time after time you hear about some sort of BUG with MS products. BUGS so terrifying that the FBI is called in because of MSOutlook or MSOffice macros. BUGS scouring the internet.
You never hear about BUGS with Linux other than minor nuisances ( all applications have minor nuisances, don't they? ).
Why in the world would you pay for BUGS when you can have a first class OS for free?
An out of the download/box Linux is usually not secure either; it has to be patched. In that respect it and Windows are in the same boat. In another respect, however, it is in a far better position than Windows: anybody who wishes can look at the source code. It would be very difficult for a mole to smuggle anything into Linux.
