Honestly, the posture thing is huge that people don't talk about enough. That hunch over a tiny screen catches up to you fast. What brand did you end up going with?

Totally, same thing happened with me and puke green.

But what if that's exactly the customer's takeaway? They see a hot, slow mess and think, "If this is brand new, what will mine look like in a year?" It sets a low bar for performance expectations right from the start. A clean demo unit at least shows the potential of the machine.
