Ever since I was a little kid, I've had to put up with people complaining about how "Linux can do this....", "Macs are faster, built better, etc, etc, etc", and other non-sense about "insert OS/platform/software/etc here". I can't stand it! (yes, I'll admit I've done a little OS and platform bashing in the past...but I've always HATED the mac and windows debate...and I've avoided it like the plague.)
To those people stuck on a certain OS or hardware platform, I say.... Give up. It doesn't matter. Try using them all. :)
Windows is good, easy to use, relativity cheap, programmable, and has extensive hardware support. It has a purpose, and it serves it well.
