Well I got my DS Lite the other day, and I must say WOW this thing is sooo bright. I started putting in my old cartridges to "see" the difference new technology makes. It was amazing, I've found that light setting 3 seems to be the best level for me. Setting 2 seems too close to the phat DS, but man 3 makes the colors so vibrant. I can't use setting 4 for any length of time it's way to bright I see spots when I look away (okay maybe not that bad, but you get the idea).
The nice thing about the vibrant colors is it makes all your old games seem new again. I put Animal Crossing Wild World in and it looks great. My animals were nice enough to tell me that I had neglected them for 3 months, but they were happy to see me and a couple new ones had moved in. There are bugs everywhere, although I'm looking for the "finned" fish like the sharks right now.
All of these snazzy DS Lites lead to one thing, theft. :) Play-Gadgets has a story about a cargo container shipped from Hong Kong full of Black DS Lites on there way to a European launch that went missing. $2.32 million worth of Black DS Lites soon to be appearing on eBay.
I'm still listening to DualScreen Radio, and the current episode 6/10/06 is a pretty good one. There is about an hour rant on Gamestop/EB Games, that is entertaining to listen to. They don't really say anything I haven't heard before, but I found it funny. I've also started listening to MajorNelson's podcast. He works at Microsoft and keeps the above blog, and also is the one that announces all the new content that gets placed on the marketplace. His podcast is mostly about the 360, and he usually has one interview each episode with someone within Microsoft. He has a DS (and loves it) so it comes up from time to time in his show.
