iPod mini
Ever since I heard of the mini, my rational side said, "that's only a thousand songs for $50 less." And I had written it off for me -- I currently have 3000+ songs on my iPod.

But then I saw it at the Apple store. And held it. And now I can't stop thinking about it. It's so small and light, and the surface material cannot be discounted.

I had been warned that this was the case, but thought I wouldn't be susceptible. Now I want one, and since I have $175 in Amazon gift certificates from my Amazon.com Visa card (credits I should be using for sensible things like books and software and music) it's very tempting. But still, I know it's going to fall in price while it raises it's capacity, so I'll just resist the siren's call for awhile longer. .. I hope.
