Well I will agree with you, up to a point though.
From the troubleshooting I have done for other people's computers I can say that, a good big portion of them are just plain morons.
They install anything and everything they see in a CD, making the Registry all fucked up. They surf the WWW with out setting up a simple FIrewall such as ZoneAlarm (you cant get any simpler than ZoneAlarm, and it does a prety good job too).
Those type of people bought a Computer from BestBuy for $2000 (maybe more) just for the shit of it. They can do their work with a 100MGZ PC, but no, they want to get fancy oh yeah and I forgot a 100MGHZ PC is way too slow for MS products.
Then we got the intermediate PC users (Where I am at right now) that have learned to do more than play pinball in Windows. They fool around with the registry and all that. That group is clever enough to switch to Linux. And from people I know in Real life and over the net, those people already have Linux on their HD along with Windows. Just so they can wet their feet.
And btw as VoidMan said, You can order any app you want for just a few bucks. And RPMs are not hard at all. I remember my 1st week with X, even though I didnt know where my head from my ass was, I understood RPMs. And trust me I am not a genious. Just an ordinary Smo Jo that was never good with PCs (former Psych Major, to give you a clue).
