XP Home should I keep it?

8. Just because XP support will end doesn't mean it will magically stop working.

I have a neighbor that still has Win95 on her old Compaq laptop. It does what she wants it to do and sees no reason to upgrade. she can check her emails and do word processing and print out letters to her printer.
you don't always need bleeding edge on applications-if the old one is working fine, why fix it.
I have a program that i use that was originally written for 98. It works fine on windows 7 X64.

One of the reasons I hate MS Office is that it is deliberately made non backwards compatible with older version documents. My WordPerfect X5 opens documents in WordPerfect 5.0 for DOS without a hitch and will open older Word and many other document formats and save them in the same format if I want.
