The Linux-guru crowd continues to discount the complexity of installation, maintenance, use, and actual cost of Linux-based OSes. 

It would be a full time job to debunk these arguments over and over again.  Occasionally, Dan takes the time to do just this:  see him dismantle another one of Joe Landman’s CCS attack pieces in Yet another poof piece.  And Dan doesn’t even mention the developer-productivity story . . .

Personally, I tend to ignore the “I hate Microsoft, Linux is the answer to everything” arguments.   You can build a feasible solution with either platform.  As Dan said in his post (specifically about HPC):

Look, I’m not deriding Linux as an OS, or as an HPC OS. It’s been very successful, and it will continue to have success.

The fact is: if you’re using UNIX or Linux, it probably doesn’t make sense to port to Windows.

But if you’re already using Windows, it certainly doesn’t make sense to port to Linux.

They are different toolboxes full of different (albeit similar and overlapping) tools.  Depending on all sorts of criteria, different organizations will do better with one platform than the other.

There is huge growth potential in the market for both platforms.  Can’t we just get past this? 

Or has this truly become a religion?
