.... Before I traded mine in when I bought my 3DS, the shoulder buttons on mine broke after about a year. Fortunately the 3DS was a right around the corner at that point, ...
im trying to understand the logic here, i assume everyone allready owned a phat, lite, or DSiXL, before 3DS was released, so at some point they made a conscious decision to either trade or sell their older unit for 3DS.
i also assume that most have dabbled in Wii softmodding, iPhone jailbreaking, or PSP CFW, so they must know that FIRMWARE IS BAD. and newer models are always harder to hack.
i can also deduce that before the purchase of a 3DS there was some compelling reason to purchase a 3DS (likely some pokemon or kingdom hearts), because at the time of said purchase they waked past the DSi section of walmart, ignoriing the DSi's for $99, the DSI XL's for $130, and possibly, DS Lites for $99, PSP Go's for $99, and PSP3000's for $129., an instead paid a whopping $250-$300 for a 3DS and kingdom hearts game.
so in other words the desire for the new kingdom hearts game completely overrided the desire for better DS flashcart compatibility on a more hacker friendly system.
