When I was a kid in the 1980s I really wanted to draw comics for a living. I spent ages sat at the family dining room table pouring my heart into little comic strips like the ones in my favorite comic books. I'd try so hard to draw as well as the artists I admired but I could never quite get there. No matter how hard I tried I couldn't match the level of detail, clarity, and expression they did.

When I was older I learned that comic books are drawn on much bigger paper than the comic. Part of the production process is to shrink the drawings to comic book size. Drawing bigger comics is a lot easier. I was trying to draw the comic and mimic the rest of the production process as well.

The same is true for dev work. Constraining yourself to what the end user has is throwing away a ton of benefits from having access to better tools. By all means test your work on a similar machine but don't throw up artificial barriers to doing good work if you don't need to. You're just trying to go straight to the final version. That doesn't work.
