Well, I am from metric country. When I was in a college studying mechanical engineering - I remember how painful this was. Imagine all our drawings, all our hardware, EVERYTHING is metric. And, they teach you about this 127 gears and imperial stuff. I was like OMG, why would we need all that? Living in US for last 25 years I got used to F, miles, inches, LBs. But I didn't get used to .0001"
I guess in school, they had to teach us all this because lots of machinery was either imported or copied and machinists had to know. Even though production was all in metric sizes.
All my hobbies revolve around cars/motorcycles. This is all metric. I am thinking metric in my head, if I make part sketch - it's metric.
Why would I want to pay extra for this? It's a pretty big purchase, and I wouldn't like to compromise on this and get what I want. True, I said I don't care about threads. But if I am going to do them - they will be most likely metric and I want lathe to be on my side (I know differences in how threads gage works based on lead screw). I would go further into saying - I don't want any of inch stuff on dials
