$600 or even $500 is WAY out of price range for me. I assume it would be worth it with Wi-fi, blue-ray and all that. But that's just shouting "Haha, you'll never have one!" to a lot of people.

Unfortunately, the only handheld I own is my good ole GBA. But I've never even seen a loading screen on any of my games which include but are not limited to six Pokemon games and Kingdom Hearts: Chain of Memories. Loading times more then 10 seconds do get on my nerves though when playing games on the bigger systems, but four whole minutes! That's painful...
