Since these items are dispersed among various threads, I think it's useful to have a maintained list of known issues that people can watch for in the early days of their ownership.
This is also meant to cover WL75(L), even though it's in the WL74 forum. Most of these are sourced from @Sarge and @Semperfi79, who seem to have found a superset of the issues identified by many others. Please append, or correct this list as needed. Note that the wide spread battery problem seems to have an identified solution. Maybe a recent software update will address others, So also strike out any that now have known solutions:
