Internet News Internet Investing Internet Technology Windows Internet Tech. My main point of contention with linux is that a lot of Linux its self and the patches are made by anyone out on the Internet that knew how to make them. The group user could have accidentally or purposely wrote a bug into the software patch doing something like giving a remote user root access. This may be a little far fetched with a Network card, but you get my point. Linux seems too DOS and end user like to me, I also do not think it is a stable.
Support is expansive from sun as well.
If you are doing straight forward stuff it is not hard on sun. You will need support when you try to do weird or hard things with it. For example, software raid is not the easiest things I have ever setup. THe other bad thing about sun is that it is really picky about the hardware it needs. If you do not care about how much you spend, security, stability, or support go with Microsoft.
