Ah, brings me back to the countless nights I spent counting plate after plate of HEK293 cells using a Haemocytometer [0], a light microscope, and a mechanical counter [1].
At least with HEK293 cells you could mostly tell if they were dead through the microscope (dead cells are darker).
I've made the same transition and feel the same way. I miss the bench, but I don't miss the late hours, vending machine dinners, and Christmas day cell culture maintenance.
