Frankly, I would take any form of sensation over nonexistence. Even being trapped in my own mind would be better; I'm confident enough in my imagination to believe that I would last at least a few hundred years before going completely insane even if cut off from all sensory input. Give me an ideal form of immortality (halted aging (likely via prevention of the gradual breakdown of biological processes) and functionally unlimited memory capacity; anything else is gravy) and I don't think I'd ever run out of things to do. Even without the improved memory, an eternal life of short-term memory loss would hardly being boring. Change it to true transcendence, and ye gods!
Maybe that's just because I'm a glutton for thought.
Give it a while and you'd change your mind.

Tell ya what. Give me, oh, ten thousand years to think about it and I'll get back to you on that.
Imagine for a moment that time did not exist where you were imprisoned. That no matter how long you were in there, you were aware that no time had passed at all, and yet all the time in the universe had passed. You can't feel anything in this prison, you can't sense anything or use any physical senses to determine where you are. The only thing you're sure of is that you exist, and someone put you there. Eventually, you're not even sure that you exist. All you can think about is who put you in here. Why did they do such a thing? Were you bad to them? You can't remember, but you're fairly sure you were good. An instant reveals itself; and eternity passes. And all you want to know is WHY. WHY DID THEY DO THIS TO ME. WHY AM I IMPRISONED?! EVENTUALLY, YOUR THOUGHTS TURN TO DARK PATHS.
