Appropriate disposal: Recycling.
Recycling plants will pick apart at the set, to separate the recyclable and non-recyclable parts and therefore you save from landfill as much as you can. Most retail outlets will accept back their electronic waste and if not that, there are local community programs that collect E-waste.
Best Alternative Edit
Consider doing without the big and fancy - most entertainment programs are available on laptops which most of us already own for work and other purposes.
