Do you bother replacing old, but working smartboards?
This is something I've never been sure about. All projectors are on a replacement cycle but for Smartboards I've only ever replaced them when they arnt working. We've got lots of 5 series boards about - they look old fashioned and the old serial cable is annoying, but technically they work fine, so in a way it seems like a waste of money.
Should I be pre-empting problems and replacing or keeping them until they die (some are probably over 10 years old now)
