I bought a pink DS Lite back in the day. Was tired of my electronics only being either black or white and wanted something less common. My wife calls it pinky and still plays it from time to time now that I've moved on to the 3DS. If I didn't already have the Zelda Edition 3DS, I would definitely consider the pink 3DS XL, but I'm sorta hoping for purple next time. :)
You'll never get your pink 3DS XL mixed up with your guy friends, but you may have to endure some ridicule from less sophisticated people. If you're man enough to wear a pink dress shirt, you're man enough to game on a sweet pink Nintendo handheld.
The only reason I didn't get a 3DS at launch was because they didn't have a pink color at the time. Once they finally announced it it became an instant wishlist for me, so yeah if you think the color's nice and you like it a lot, just go ahead and buy it.
For the record I'm a young woman who games and I had had HAD to get the pink and white 3DS. It's perfect. I had a pink DS lite (the pearl pink version) and consider this particular shade to be even better.
