Re: Why Linux sucks...for now.
We do the same thing here with our Linux distros - every one is custom-built for our environment. You are correct, though, that Linux is more secure mainly due to its low market share. If it had Windows' market share - or hell, even Mac's share - it would be much less secure than it is now.
Unfortunately though, it's going to be a while before some companies get really serious about Linux support. Obviously Linksys and Creative don't really care about Linux since most people have never even heard of it, much less use it. So they won't put much time or money into improving it - at least for now.
