I don't want to back seat moderate but i'm assuming most moderators wont see this being this old. You're not supposed to post in month old posts. If you hadn't quoted me I wouldn't even know about it. Just a tip.
It does blow some air out the front because that's were it vents. But not enough to blow away dust. As far as tethering its not bad. It is slightly more stiff than a power cord, but not unruly.
Sorry, I was interested and it didn't seem that far down the list. I'll stop posting, sorry again.
