A time to dump XP?

I was reading on slashdot about dumping XP
Maybe it is time! and not to w7 but to a real operating system
Ubuntu is ready for the desktop, I now there are comments like "missing apps", "no games" ...

Most daily work can be done out of the box on Linux
"office", "mail", "surfing" can be done without a problem

Migrating from XP to Linux is for most users not a big problem,
Even my mother is using Ubuntu for 3 years now
She migrated from XP to Ubuntu gutsy and I just needed to give some small explanations about evolution mail and firefox

currently she works with Lucid and firefox, amsn, evolution, picasa, gimp and ooffice

so idd its time to drop XP :)
