Moving from Windows to Ubuntu is an option.
Many have older computers that are not designed to run Windows 7 or Windows 8.
I've seen computers on the curb that would be great Ubuntu systems if only people knew they could format that Windows XP off their systems and install Ubuntu operating system.
You'll like the package once you find the start button and make your desktop yours.
Then when you donwload OpenOffice or LibreOffice you'll have all the document software you need.
And yes, simple games as well.
So why are you kicking up dirt and saying you aren't going to move away from Windows XP because of the costs?
Maybe you should think about the software issue you are going to experience.
When XP is officially not supported every hacker in the book is going to be targetting Zero Day exploits on computers connected to the internet running Windows XP.
Why not do yourself a favor and all the people that share the same interent a favor and start planning to upgrade this week to Ubuntu 12.04 LTS for 32Bit systems.
If you have a 64bit computer you can install that as well.
Let me seal the deal with your upgrade to Ubuntu.
You'll be able to install VirtualBox and run your Windows XP software (if you have the install disk still) on your computer. That will give you time to move things around.
You can have someone setup your VHD and clone your drive.
It's easy, really, I have people that never used Ubuntu before loving it in just a few minutes.
And when I say Loving it, they seem to no longer complain about things not working like in the old Windows XP world.
But, be careful when upgrading, you need to list all the software and applications you currently have and find replacements that are free for the Ubuntu operating system.
I'll help if you ask and need advanced support.
