Interesting thing Greg,
Commercial here would be the likes of office buildings and light Industrial, with respect to a few socket outlets and the odd computer network.
Industrial however is a totally different kettle of fish, this entails factories and other such technologies, PLC's even control systems that don't use PLC's.
SLC's (Small Logic Controllers)(almost a smart relay) are becoming more prevalent here for smaller processes.
At the old newspaper place that I used to work in it was very handy to have your own lap-top computer, you could download data off of the gear there and see it on a lot larger screen than what the SLC screen gave you.
What's more, you could save it and have a look at it later on, maybe when the thing broke down again, but with a different fault.
Just my $0.02 worth.
