On my trip to Canada my dad had to renew his fishing license, and they had an XP running for their database access website. Sorry, no picture, there was like 5 people in the way.
Also I went to Canadian Tire, and while there was no XP in sight, there was some interesting stuff.
An IBM Dumb terminal!
Looks like it's connecting to a mainframe (or something emulating one) to manage inventory
Also I found an Dell OptiPlex 740 stuck at the BIOS screen, almost looks like a good chance it could have XP on it
And, finally, a price checker running what appears to be an XP-era version of windows CE
