My Second Life character looks and acts exactly like me except he can fly.
I have both the Funai and a Roku in my home. I love them both.
Roku does not have the ability to play YouTube, Funai will not play Crackle. They both play Netflix, Hulu, Blockbuster, and many more.
Funai has pod casts I cannot get on Roku, but Roku has more channel options (particularly the private channels).
Both are great, both have limitations, both are appreciated in my household.
