I like how savestates make things easier though.  Of course, you could always disable the savestate keys and stick to the ingame saving mechanism if that suits you.
Some parts of a game which would take lots of practice for someone like me who keeps making mistakes can get really irritating, so a savestate feature where you can easily correct a mistake makes things more interesting IMO.

Some people consider it cheating, but I don't, rather, I think of it as saving time trying to perfect yourself.
