We use them here without a problem. ...we just recently had to recover
a database to a point in time prior to olap going bizark. Works fine if
you have the disk space.

The usage that I've seen and used is to start with a level 0, and from
there on out you'd only take level 1 incrementals. Then, based on your
recovery window, you could roll your base backup image forward, for
example to 7 days ago, if that is your window. It saves you the time of
not having to do another level 0, but having a recent level 0 image to
start with for recovery.
The reason I stopped using it is that you HAVE to do a backup COPY. I
didn't have the disk to hold an actual copy, and needed to have
compression.
