Have considered changing my initial order for a BDP-1 to a BDP-2, but, like you, liked the original idea of attaching HDD without the need for setting up things and streaming stuff all over the home network. So far I am completely happy with my choice. I tend to play albums, or complete opera's, so I do not switch a lot. Use the 4 button navigation for that, but will see if I will upgrade to a dedicated router. Can attach 2 x 1 Tb drives which hold more music than I possibly can listen to in many years. Have no need for more storage.
Do not even use the radio feature, as the squeezbox does this quite well (connected to the BDA) and adds the diversity of Spotify.
The sound of the BDP is glorious, so I could not be happier.
Just one question: why did you go for the BDA-2?
