Do the advantages of Moving Map PNAs outweigh the disadvantages?

Absolutely without a doubt PNAs are the way to go. This is along the trajectory from compass+map, to bearing+distance (303), to not-so-bright displays (PDA and some PNAs), finally to the super bright PNAs.

BTW: What disadvantages do you speak of? There are some but I'm interested in your take.
