It would be nice if it was easier to have a setup which is fast for development but realistically slow for testing. I develop my personal website on a 6-year-old Windows laptop which was only $750 at the time. It definitely keeps me from making a slow website! But it also makes my devserver much slower than I'd like. I wish I could have speedy tools but a slow browser (and no, Chrome's CPU throttling isn't really the same as a truly crappy computer)
