I'm trying to think which will go longer (part of the least failure bit), hence my emphasis on reduced life expectancy from heat.
Speaking of case, that's another important point; I can't bear the idea of going caseless, dust build up is going to cause problems as well.
This is definitely giving me flashbacks during my time in the corporate world. There was one report that was replete with copy and pasting, the poor lady who used to do it apparently had to pull all-nighters doing it. I rebuilt everything in Access using some SQL and the new process only took 15 minutes to run.
