I assume that you meant to say Windows XP is the WORST thing Microsoft ever made, not the "worth". Of course that's still so unimaginably stupid that I am cursing you continuously to Heck even as I write this. Windows XP is a good operating system with few bugs, the only problems now are with Viruses. Windows XP isn't the only program susceptible to viruses, everything is. I'm amazed there hasn't been more deadly problems. Also, if any other company were leading the market, they would be attacked just as much, and would have the same problems Microsoft has. It's taken a long time to get to Windows XP, and it's finally a working operating system and I'm happy with it.
Also, if you own a computer, you're rich enough to buy more RAM. You can get RAM incredibly cheap from Tiger direct.
EDIT: Here's a run down of a conversation I had with Clokr_ on MSN:
"it stores by default lots of

for restore because it thinks that you have a 120GB harddisk"
First of all, it stores the information on a secondary hard drive, and the feature can be turned off easily in System Settings.
"I like the square windows, are more profesional"
You can revert to the Standard Windows look in seconds by right clicking the desktop.
"IE crashes lots of times for me"
Spyware issues.
"some games dont work"
I asked him to name some examples, he couldn't. Even if he's telling the truth, I had the same problem, but it's not Windows XP. The fast paced gaming world of today requires terribly powerful graphics cards, and onboard system video of something like 8mb isn't going to cut it... I bought a 128mb Radeon graphics card, everything runs smooth.
