Actually there was a poll earlier that showed the majority of people on these forums think it was a good idea to change. The rest either just don't like the idea because they preferred attributes, don't understand it or don't like change because they are bound by nostalgia (which seems to be a rampant problem *cough* Morrowind *cough*.
I'm one of those people who think Oblivion was a huge step back from Morrowind's RPG game-play.
But I think Skyrim's changes are all for the good, and they have learned from their mistakes in Oblivion, and they have stated the fact several times in different interviews, sometime under cover and sometime completely open when there was no denying it.
So yeah, I think that the new system is great and addresses a lot of game-play issues, like:
Playing for the sake of increasing attributes, as compared to the play for the sake of getting better in our actions and developing our character's effectiveness and general standing compared to the world.
Previously you had to use Bows all the time to increase your agility in order to become more effective in sneak, now you only have to sneak around as much as you like, so no double tier of bounded skills to force you do things that you might not like.
Now you can make effective sneaky characters that do not use bows, but slit throats from behind, or something like that.
You can now make characters that use any combination of skills as you like and as effective as you make your character by practice.
And your character would grow and advance in levels naturally along the way, as you use your skills, and is not hampered by a predefined class, that would force you use non-class skills in order to gain maximum attribute points in the level-up sessions.
In effect you define your class in playing as you like, so if you play like a thief then you advance your thiefly skills and are in the thief class, and so on...
This is the best vanilla leveling system of the elder scrolls series yet!
