The software is great but the pen interface really is not practical
in-flight. CBAV is tough enough but you only need to access that once in a
while; a GPS requires far more frequent button-pushing and becomes much more
a part of your routine -- with a Garmin 196 you will essentially gain not
only a GPS but also an HSI.
Go with a dedicated aviation GPS.
