What’s the problem with Linux?

ContractorUK.com gives a good case for why you should or should not move to Linux.
The article reads, for example: It is cheap. But not exactly free. Linux has been personally adopted by users and IT communities around the world, partly, at least, because of its supreme stability and security.
According to Michael Robertson, founder and CEO of Lindows.com: “Lindows (and other Linux versions) follow open standards. You don’t get locked into a proprietary, monopolistic system where the software vendor has more control over your computer than you do”.
There are also very few Linux viruses and even if your system has a virus, it cannot spread it to other machines.
