Re: Slow is fast
years and years ago, a colleague and I developed on the fastest desktops we had - whheeeee
Out main test desktop was an old, ancient no longer used, well underspec unit. We made sure it ran fast on that before passing to users
Even now with SaaS etc. At one point at a client we tested the mobile app on a crap mobile with limited screen size and data transfer speed. We optimised where we could, we compressed where we could. It can be done, just not often. Dekstop users at that client loved it
