From a backup/restore perspective then, especially to try to restore a portion of a system to a certain point-in-time, is thereany reason to use Filegroups?
No. If you're required to be able to restore a subset of the data to an earlier point in time, you need separate databases, not multiple filegroups.
Filegroups have lots of uses w.r.t. backup/restore, but your requirement is not one of them.
