I have to disagree with your post on a few key points Yoshi.
Nintendo isn't targeting casual gamers with this system, really. Have you looked at the release lineup of games? Of the top titles, only Pilotwings is geared at "casual" gamers, and even then, I know plenty of longtime gamers (read: since the NES days) that will get it.
Pilotwings is hardly a title geared towards casual gamers, IMO. That said, the 3DS launch has plenty of titles that I would consider to be games for the casual crowd: Nintendogs + Cats is chief among them, but also Lego Star Wars, Super Monkey Ball 3D, The Sims 3, Madden, etc. That said, the 3DS actually has a very nice range of titles in its launch lineup, even if most of them are games that appear on other platforms.
Are you kidding? Unlike iDevices' touch screens, the stylus gives a preciseness to the device it wouldn't otherwise get. Also, why would you want to cover important data on the bottom screen while swiping with your finger? That's one of the reasons I don't buy games on my iPod Touch: my fingers cover up too much of what's happening. A stylus allows you to continue seeing what's going on.
I find that the stylus on the DS gets in the way just as much my finger does on the iPhone, and that the Apple devices are in general surprisingly accurate and precise with touch controls - but that's just me.
Wait wait wait...you're expecting these huge games to be entirely downloadable immediately? Tell me when brand new PS3/Wii/360 games are being digitally downloadable. I'm not talking about PSN/VC/XBLA games, I'm talking about the Super Marios, the Call of Dutys, and the Halos. You can't download those
You're completely wrong and misinformed on this one. The last few Halo games have been able to be downloaded on XBLA, Sony did this for MAG and Mass Effect 2, and there are many many other examples. Sure, these downloadable "box games" take up plenty of room on a HD and can take ages to download, but many games do indeed now have a release day digital release. The same applies to a bunch of PSP top-line titles. I agree that Nintendo really should have provided this option, even if it isn't one I'd ever use.
Anyway, I'm not sure that your comment should have been taken down, but some of your info was
