USB mini fridge - is it really worth it?

I tend to get in a rush when I get home from stocking up on food for the week, so I tend to forget to toss my Mountain Dew in the fridge. So then when I get thirsty I get to play the freezer game where I put it in and try to remember to take it out before it becomes a big chunk of ice.

This little USB-powered fridge is big enough for one can of your favorite caffeinated beverage and sits at about 47-degrees. I'm no mathematician, but I'm pretty sure that putting a can of pop in a fridge at that temperature will take a while to cool down to where it's good to drink. Not to mention this thing is likely going to suck about as much juice as it possibly can from your USB port.

I'm not sure that it's worth the $33 price tag, it seems like a good idea, but I think I'd rather just get one of these instead. It's quicker and cheaper, plus it doesn't take up one of my precious USB ports.
