Since a lot of airlines are already offering WiFi connectivity on board (except for take-off and landing), one can only surmise that electronics with no WiFi or cellular connectivity should be quite safe to use.
Another factor is that a change in safety regulations for aircrafts entails a very long and convoluted approval process where different levels of interference would have to be shown to cause no effects for each type of commercial aircraft. There are also older planes with anlog equipment still in use that are much more likely to react to interference -- again, the rules need to be consistent for the general public.
The NYT has a nice article
about the issue.
