Let's face it... There's a billion reasons to use this. Not having to constantly hook up a separate cable. It's convenient. It's stylish. I can play Roms using my WiiMote (since the Evo's been rooted).
But the big thing is... IT'S FREAKING COOL!! I love my Evo, and I want to spoil it in every way and shape possible! Cool cases, cool backgrounds, cool apps... I just want to show it off and bask in the jealousy of all who know me.
I WANT TO BASK IN IT, BLAST IT!!!
(ahem)
I think, a device like this, gives your Android phone more substance in the home, and it doesn't just lay limply plugged into a charger on your nightstand, but stands out as a component of equal worth as your DVD player or XBox or whatever. My Evo deserves that kind of recognition.
Thank you for your consideration.
