Well, I would be using the PS2 homebrew apps if my ex-girlfriend would return my PS2 (she refuses to do. I asked her 2 months ago to return it and she refuses, she moved 1 month ago so I don't know where she lives).
So, for me, I'm getting my emulators and homebrew on my 60 GB PS3 thru Linux but since my PS3 plays PS1/PS2 games, I'm playing PS2 games on it.
Heck, I remember the fun I had using the PS2 Independence Exploit to play Beats Of Rage on my PS2 years ago, boy that was fun.
