The "W" version has the built-in WiFi, the first "in-house" (non-OEM) Ricoh camera that have it, still good because very late is better than none! :-) NFC is still lacking, though, unfortunately. Moreover, do also note that the WG-30s do not have any GPS receiver built-in, which is really not good for an adventure camera which it is meant to be.

Wifi is a must for an outdoor camera. I really don't realize the Ricoh's marketing strategy on this WG camera....
