True, but I'm not confident I'll find one: the particular Samsung model I have doesn't have bluetooth as listed in full specs on the Samsung website, which makes me believe the seller simply ignorantly posted the wrong specs, and an exact internal adapter for this exact model might not exist.
Also, I can't get 4.0 that way: after hearing your advice, I'm tempted to purchase a combo wifi/bluetooth 4.0 mini pci card
and swapping that with whatever I have now. I really need to brush up on my hardware know-how, the usb solution I initially proposed was pretty pathetic vs this
