I also multi task. I either watch the anime on my PC, or listen to music (usually PokéSongs in Japanese), or watching YouTube videos. I also have Serebii or any other PokéForum on, or various online stores that sell PokéMerchandise - while playing with my Nintendo DS Lite or 3DS XL.
I forgot, the only times I don't watch anime or YouTube or listen to music is when I'm watching the actual TV - everyday at 4:00pm the local news, and Mondays 6:00pm to 11:00pm Lizard Lick Towing, Tuesdays 6:00pm to 11:00pm Hardcore Pawn, Wednesdays 6:00pm to 11:00pm Operation Repo, on TruTV.
Its how I spend at least 14 hours a day - almost every day, except when I work or have to go out of the house.
