I think it’s worse than just that the icon doesn’t convey the program’s purpose: it looks way too much like a flatbed scanner. I appreciate the difficulty in crafting a descriptive visual representation of a BT client, but IMHO an icon should at least be sufficiently unique so as to avoid mistaking it for other apps of completely unrelated purposes. That’s where Vuze’s frog for example is better (as long as you’re not into Frogger clones). I’ve been running Transmission whenever I’m logged in for years now, and I still occasionally wonder why I have a scanning app running, when in fact it’s just Transmission’s… I’m-not-sure-what-it-is.

I realize this is not a very constructive argument so long as I don’t have anything better to suggest in the current icon’s place, but I promise I’ll start thinking of one right now and hopefully come up with ideas some day.
