My reasons for not wanting a DSi are pretty simple. I already have a DSL. The DSL doesn't get firmware updates, which means it will NEVER be made to block flashcarts. Anyone who thinks they are safe with flashcarts on the DSi just because the couple of FW updates it has gotten hasn't blocked flashcarts yet is fooling themselves. They're playing nice right now, but once the DSi starts selling and reaches numbers near what the regular DS has, and they completely phase out the DSL's, and a few more DSi compatible flashcarts come out, then they'll start working on blocking flashcarts. Think of all the flashcarts that were for the DSL right now that are junk in the DSi....
DSiWare......sorry, I ain't paying for downloads. DSiWare is nothing more than a way for them to sell you something without having to provide any physical material (case/cart/manual) and to make it more difficult to pirate. From a business standpoint, that's all well-and-fine, but from OUR standpoint it just means we'll be forced to actually buy the games instead of just sucking them up for free on the net. (@anti-pirates, take your morality and shove it) Then there's the possibility of them providing GBA games through DSiWare. YAY! Just want I want to do, buy games that have been around for years, many of which I already own, just so I can play them on the shiny new DSi. But wait, the game I already own is useless with the DSi. Can I send them my cart of the game and get a free download of that same game for the DSi? Nope.
Removal of the GBA slot - I can understand this from Ninty's point of view. Why bother continuing support for something they make no money on. Still, it's a deal-breaker for me because I only got into handheld gaming about a year before the DS came out, so there is still a lot of GBA games I haven't played and I still want to play. I'm sure there are a lot of GBA games that I'd like that I'm not even aware of, but if I dumped off my DSL and bought a DSi, I wouldn't even have the chance to play them. I don't want to have multiple systems for this-and-that game when the DSL I already have does it all already in one handy unit. Besides, there are games and various homebrew which makes use of slot2. I'm not ready to give up over half the library of games the DSL has to offer just to have the latest handheld.
Those two 0.3MP cameras in the DSi?
Pfft.
The ONLY benefits of the DSi I can see are the larger screens and better sound and that's not enough for me to consider buying one. I can see the regular DS's screens fine and I usually have the sound turned down below maximum anyway.
I could go on with my suspicions on what the DSi is really all about, but most people have already made up their minds one way or another about the DSi, so I'll let them argue amongst themselves while they weigh the pro and cons. I'll let Ninty show everyone why I won't bother with a DSi. Don't think for a second that there isn't a very carefully thought out plan behind the DSi. Conspiracy much? Well, maybe so, but that doesn't change my opinion.
I don't really hate the DSi, I just couldn't care less about it. It just doesn't seem practical in any way, shape or form, especially during this recession. I can't afford to waste money on superfluous unnecessary's. A good working flashcart is infinitely more valuable to me than a DSi.
