Yes - those are two things that specifically make it harder. But, in the first case, they heighten the anticipation and tension as you watch your bird go up and then come down three pixels off. Frustrating, but I'm willing to bet it sucks most people in.
Similarly, I find the lack of fine control to be frustrating - when I know that I want to do the same as I did last time (but with the third bird a pixel higher), but can't quite judge it right. But I suspect that this actually makes it fun to a lot of people.
I suppose the bit about having to repeat your first two shots with a nonzero error rate in order to try a new idea for the third is conceptually not all that different from any number of games from the 8- and 16-bit era, where you always had to start playing from the beginning and only by getting really good at the first n levels could you get a decent number of chances to try the (n+1)th, and even then you'd have to slog through the first n all over again every time you died.
These days people don't seem to be quite so willing to put up with that (there's scope for dispute about whether you should be allowed to quicksave every ten seconds or whether there are time or space limitations on saving or whether you just get the right to go straight to any level you've legitimately reached, but pretty much all modern games have to have some sort of means whereby once you've reached level n+1 you can play it over and over again without having to go through the previous n every time). I suppose Angry Birds gets away with it by having the repetitive retries be seconds long rather than hours.
