Anyone who was expecting a lot of exclusive games was kidding themselves. Similar systems, DSi for instance, never had many exclusives.
As for the point, the OS is faster, the 3D is better, and there is a (sort of) second analog. If you play the 3DS alot and in 3D, it's a nice upgrade. If you don't have one yet, it was clearly better than the XL. If you own an XL and don't use it often or in 3D, it's not worth it.
Not every product has to be for everybody.
