So I've decided on getting one of the three Bluetooth adapters: 

Asus:  http://m.ncix.com/products/specifications/85678

Iogear: http://m.ncix.com/products/specifications/80645

Iogear: http://www.canadacomputers.com/product_info.php?cPath=27_1048_715&item_id=NV8359&sid=ungv0d288gdn07ihaf1sdcp354

 

Which one is the best? 

Thank you for your responses. :)
