Gee, by that standard there isn't ANY operating system that works.
For instance, here is a FOUR PART TUTORIAL on how to install Windows 7.
That's right. A four part tutorial. On how to install just the OS. Installing an office suite, a decent email client and web browser not to mention all of the addons required to actually put a Windows machine on the Internet (spyware remover, anti-virus, firewall) are NOT part of the FOUR PART TUTORIAL.
On the other hand, I can boot a Live CD of Ubuntu and be on the 'net, browsing web pages, sending email and creating Word documents and PDF files in under 5 minutes.
Then why does “ubuntu’ (who dreams up these silly names anyway) have such a small share?
