IT - Stupid Question about NAS

Maybe both of us need to look into something like this:

This would be the best solution, on paper, it seems. It would pick up my wireless, which would then allow it (the TV via HDMI to the DLink box) to connect to my NAS. Boom. Done. Or I could hard wire it to get even better transfer rates via a 1Gig connection on a nice new Cat6 cable. Plus, it would allow me to give them my 26" and get myself a nicer bigger monitor for my room instead of having to buy a new LCD TV for them with an ethernet port. They don’t watch TV, it’s strictly for stuff like Planet Earth and family videos for when people come over, so they don’t need a 60".
