I voted not to take it. Our senses are deeply integrated into how we interact with the world around us, and it can be very dissorrienting when any of them become disfunctional. I recently experienced a temporary loss of hearing due to an attack by mutant earwax buildup. It was a very weird, disconnected, fuzzy-headed few days until I got them syringed at a local hospital. Not something I'd like to repeat.
Also, I now have Type II diabetes, and the possibility of maybe going blind someday terrifies me. There's so much color and beauty in this world, I don't know what I'd do if all I had to look at was inky blackness for the rest of my life.
Without a sense of touch, our whole bodies would feel numb like rubber. It'd be much more difficult to grab or hold onto anything if you couldn't feel it in any way.
As for the sense of smell, think of fresh baked bread, hot apple pie or pizza, fresh-cut lemons, hot chocolate or coffee, or all the scents of the changing seasons! Who would want to give those up? Being a big bibliophile, one of my favorites is the musty smell of an old book! I love the smell of old bookstores! Aah, good times!
Still, a new supersense sounds interesting. Being able to experience the world in a whole new way would be very mind expanding. If it required destroying one of the basic 5 senses though, I think I'd have to wait for next years' model after those bugs had been worked out.
If your sense of taste were magnified though, you would be able to recall vividly pungent flavors rather than have to recall the scent of foods which is almost like a temptation. Imagine being able to conjure the flavor of pastries or gourmet dishes without the need of worrying about the caloric intake or their lack of any nutritional attributes other than psychological enjoyment.
