Nintendo DS Improvements

In light of Nintendo's upcoming 3DS handheld, I thought I might ponder some improvements that could be made on the current 25 versions of the NDS.  Nothing new or groundbreaking here, just my personal opinions.  I can't wait to see what E3 (2 weeks!) has in store, but I think I'll have a hard time keeping up with my posting at the rate they typically release stuff at this conference.  That's tangential to my primary story however, we'll get there in due time.  Let's start with the DS.  I own two of them, the original, and the Lite.  Between the two, the Lite marks a considerable improvement over the first, or the Phat, as it is referred to by some.  It's smaller, lighter, brighter, and altogether more pleasing to the eye.  After that, the DSi was introduced, with two cameras, web browsing, downloadable games, and an all new firmware on top of a thinner, lighter still frame and 3.25" screens (up from the 3" screens on the Phat and Lite).  Now, right before the official announcement of the 3DS, we are treated to a new version of the DSi, sporting everything the current i model has, but in a much bigger size.  4.2" screens are what this behemoth offers, Nintendo says to cater to the older crowd of DS gamers that have had a hard time reading text on the smaller screens of past iterations.  Now's when I state what I would like to see improved on the next generation of dual screen handhelds from Nintendo.  I personally think that the idea in and of itself is a great one, there are several games I love to play on the DS, but like many Nintendo systems, the best games come from Nintendo themselves, that is to say the games that utilize the touch-screen the most, and the most graphically taxing, showing what the DS is capable of pushing to those 2 screens.  In my opinion, making the screens bigger is a great idea, but leaving the resolution at a miserable 256x192 is pathetic.  It's understandable to leave it at this stage in the handheld's lifecycle, but I'm talking about the future here.  If we're going to be playing games on two 4.2" screens, they better at least have the resolution of the PSP's screen of similar size, which is nearly double that.  Also the same size screen on the HTC HD2 is nearly double the resolution of the PSP!  Clearly Nintendo is a bit behind on that note, but I'm sure they've noticed.  The graphics processors are also severely outdated at this point, clocking in at nearly 100MHz and 80MHz respectively, when we have feature-phones with 500MHz processors now (there is one in my desk drawer).  The graphics are by no means bad, there are some fantastic looking games on the DS (Metroid and Mario 64 I'm looking at you).  I don't think anyone would object to GameCube level graphics in a handheld, and I know they could do it.  Nintendo has a habit of not focusing on performance as much as gameplay, but their games typically tax their own systems the most, and it shows on this system and on the Wii as well.  Again I'm not talking about changing the current system at this point, and I know that with the lifecycle game systems generally have, they are outdated before they are released, but Nintendo should at least be working to put itself ahead at the point of release.  A capacitive touch-screen would also be a welcome, much more finger-friendly touch to future iterations.  Now I applaud Nintendo for keeping themselves at a point where the actual game-play is more important than graphics, and I love to play most of their games no matter how they look.  That's one thing they know how to do, and do well.  I'm not sure what to think about the idea of a 3D handheld, not to mention a dual screen handheld, but I'd be lying if I said I wasn't interested in seeing what they've come up with, and how it will treat all the games released to this point.  All in all, I'm pleased with the DS that I own, and the games that I have as well, but I think that Nintendo should be working on the next generation and making it competitive on all fronts instead of releasing so many different versions of the same thing.  Do it right the first time and we don't have to have three different versions on store shelves at once!  P.S. - Keep the throw switch from the Lite, not the power button that you can press accidentally!
