I bought it originally to play the graphical upgrade of one of my favorite games of all time, Ocarina of Time. I bought an XL because it had a lot of great games and more great games coming and I wanted to experience them on a better, bigger screen. Also the XL is more comfortable to hold and has a vastly superior design and color scheme to the original 3DS line. In general I've also had at least one iteration of every Nintendo handheld generation starting with the Gameboy Color I got for my 10th birthday along with Pokemon Yellow.
Basically a Nintendo die hard to the bone... can't blame you, they have nice handheld games since ever =]
Totally. :D Between my brother and I, I've also had every one of Nintendo's main home consoles (except the Virtual Boy...) from the NES through the Wii U.
3DS, though, is the first and ONLY time so far that I've ever double-dipped and bought a 2nd/upgraded version of any piece of Nintendo hardware. Worth it!
