Not at all. In fact, good news! Someone already explained it for you.

I hate to say this, but those threads made it no clearer.
From reading them, I don't think that USB debugging in the issue, and if it is, then what the hell is up with Android?
What I sought to do is not at all exotic -- I have songs and photos on my home computer that I'd like to transfer onto my phone.
Android can tell me where I am, what the temperature is, sync all of my work emails, contacts and calendar, etc., but I can't transfer an MPEG or a JPEG from a hard drive to an SD Card?
I don't need to sync with my computer; I just need my phone to show up on my computer screen so I can transfer files to it.
Maybe it's all Apple's fault and it's just a lame attempt by them to prevent Android from poaching Mac users, but I would still think that it would be a first order of business for Google to program around that.
That's all I'm saying. Again, thank heavens for the folks at Double Twist.
