Why wouldn't you want the XL version?
I'm OK with them not including adapter. The screwdriver to get into mSD is weird to me though.
I overall preferred the XL to the OG 3DS. Even though screen loses quality, I liked the bigger screen. I thought the ergonomics were much more comfortable, and easier to play for long sessions on the XL (OG was too cramped). Although I think the N3DS small would have helped that out.
The battery life on XL was also better. All in all, XL always felt superior to me. And I suspect, many felt the same way, as I think it sold much more than the smaller 3DS in the US (maybe I'm wrong on that).
All that said, plenty of reasons someone wouldn't want an XL.
* N3DS small has better quality screen (PPI, tighter screen).
* It's more portable. Can actually fit in your pocket, or bag easier then XL. Very light.
* It had faceplates, which allowed you many diverse choices. Whereas the XL basically boxes you into picking either Black or Red (basically, no choice at all when it comes to color).
* Those with smaller hands, might not be able to play the XL for long sessions (the reverse problem some had with the smaller feeling too cramped).
* Lastly, some say the smaller/tighter screen means the 3D works better. I personally don't agree, as I've owned both. And I actually thought the bigger screen worked better for me. *shrugs*
So yeah, in the end I always wanted an XL. I was highly considering going back down to the smaller size with all the changes and perks. But eh. I still understand why many DONT want the XL.
