>IMO, this is one of the big problems with Linux. If you have the source code, it should be easier to hack. Linux fans will say that there will also be more people out there to plug the holes, but your OS will be accessible until those holes are plugged.

Craig, I come from a Unix background. Most of the web is made up of Unix/Linux OSes running Apache Server. If you look at the hacks, crashes etc. you will find that a very disproportionate is MS with IIS. I have confidential files in terms of patient appointments etc. Do you really think I could rely on an MS OS with IIS to say put a program on the web where patients could add, change or cancel an appointment. I think I would lose my licenses very shorthly for violation of confidentiality.
