So these 360 HD DVD drives can be used as external PC HD DVD drives?

I had been watching the LG internal combo drive prices, but for a measily $50, I just ordered two. I wonder if I should now bother with the internal drives. Then again, this thing is not powered through the USB...
I will say that the idea that you can save your HD DVDs to a hard drive and probably burn them to BD-Rs in the future might help if you don't have a BD player in that respective room. Would be easier than carting a player around (I absolutely despise having to dig in a cabinet and rearrange cables!).
