It looks like Nokia Lumia 800 will support USB Mass Storage mode for consumer convenience. Itâ€™s official product specs page revealed this news and on the storage front both the Nokia Lumia devices wonâ€™t support external memory cards.
Thanks to everyone who sent this.
Update: I forgot to mention TV Out feature in Nokia Lumia 800.
Update 2: Nokia has updated its specs page of Nokia Lumia 800. Sadly, It won’t have USB Storage mode and TV-Out feature. Why Nokia ? Why ? 🙁
