Bad for what? Gaming? No argument from me, but for anything else it's more than capable. I have it on three different computers, including the one I'm using now, and haven't encountered anything I can do with Windows that I can't do with Linux. I could list all the reasons that I prefer Linux but if you can't find your own, then stick with Windows. I've read some of your posts about setting up a server and I didn't see a mention of Windows Server. What's up with that?
And really, making a statement like "Linux the worst OS ever.." doesn't even rise to the level of childish.
