Entertainment
Audacious Music Player (and I have almost 2,000 songs on my dedicated Media SD Card in Slot 2)
VLC/SMPlayer2 - haven't decided which I want to use yet for videos, whichever I can make work with my TV-Out Cable...yes I have one.
And that is most of it, there are a few other things in there that I'm using and didn't mention, for example, PanDafe...which just puts several emulators accessible from one icon.
So I am getting a lot of use and versatility out of my Pandy...and I'm not even using Android, DOSBOX, or any other alternate OS, like QEmu.
Oh, and I am about to add EasyRPG, because I have a couple of RPGM2K I like and would like to play on Pandora! and another game is being programmed for that by a friend of mine right now, I can help him beta-test it on my Pandy!
By the way, for all the use I am getting out of my Pandy...this is probably less than 10 percent of all it CAN do.
So if I hear one more person scream about the price....
