Personally, I see more uses than just for low-end computers or servers. For example, Media PCs. Many codecs seem to work much better on Linux than they ever could on Windows, not to mention the extra space you'd have for storing DVD rips and such.
lighter weight resource wise too, my netbook only has 1gb of ram. half of that was eaten up by windows, now i've switched to linux and i have 90% left over for me.
course, that's the low end computer argument
In case you're blind, every time Setro is met with an issue he just goes "forget it" and decides to do something unnecessary. Not to mention the fact he didn't even seem the least bit concerned when people told him it was a RAT
he did do this
so yeah
