Is that really notable? They are both small numbers, and those NT machines are likely at companies with upgrade policies versus people who choose not to upgrade their personal macs for free.

I see this rather in favor for Mac OS X as their upgrade system definitely works, 10.8 is not old at all (2012), Windows NT is from the 90s mostly pre-internet. It's putting things into perspective.

It also shows what a solid OS Windows NT has been :)

Also there are many valid reasons to not upgrade from NT...

Not if you expose your machine to the internet!

I wonder about NT with nothing but up to date ssh exposed vs win 10 with nothing exposed except the pile of obscure phone home protocols you can't turn off.

I suspect NT wins unless there are unpatched TCP/IP exploits.

I wonder what percentage of in-use ATMs make a similar bet.

~0, because ATMs are not connected to the internet.

Not sure if you are serious. But a OS without security updates for years is almost always much worse.

Windows NT 4.0 - deploy and forget. Maintian only when some hardware breaks.

There are some nt machines chugging along doing specific tasks that will outlive us all.

Make sure to reboot every 2 billion seconds, otherwise weird stuff stops working... Maybe it's only UI, though.

Led a netware 5 migration from NT4 and NT 3.5 in 1999-2000. Some people then would have disagreed with you. :)
