Just saw this on his Facebook:

Dad's 6 year old PC had a virus & was inoperable...Three hours later,
its a system restore to factory settings , patch updates, and it runs
like a dog.....New Computer ? Another restore ? Ubuntu to the
rescue....30 minutes later a perfectly fine running desktop running free
Linux...taking down the evil empire 1 PC at a time...

Can I live with Linux?

Thunderbird and Firefox will probably be OK but what if I need to run
others like Turbotax?

Any thoughts?
