I can't believe I'm bringing this up, but the Arnold Schwarzenegger movie "The 6th Day" really matches my views on the subject, and also matches your views.
(Obvious spoilers for the movie)
In the movie Arnold is cloned, wakes up later, and goes about to find out what's going on. At one point he finds out HE is the clone! Back to our discussion. From the point of view of the Copy, the procedure was successful - the consciousnesses was transferred to the machine and the copy continues existence. From his POV he does wake up in the computer after the procedur. For you, though, it's a copy that wakes up. Perhaps your brain is destroyed during the upload process and you stop to exist. For the copy you (that is, him) continue to exist and avoid brain death.
If a scientist asks you, "Was the upload successful?", you (the original) will answer "No". The copy you will answer "Yes".
