Is WIFI on the watch any useful for Connect IQ 5 apps?


I am just wondering, if I should get a 255 with or without Music/Wifi. Is the Wifi function in any way useful now or in the future for any kind of apps which might communicate directly via Wifi?
Or is there any kind of function next to Music etc. which speaks for the Wifi in the Music version to be preferred to the "normal" watch?

Thanks for your thoughts
