Sure have.
I suppose I got to about level 45 or so legitimately. But by then I'd already leveled up all the skills I was going to really use for the game. So yes, I did that bookshelf glitch with that ugly book whose name I forget to get everything to 100 and my overall level to 80 or 81. But I was also over 100 hours played and nearing the end when I did that.
The only other way I could be said to have "cheated" is I took advantage of that "Free house in Whiterun" exploit. But that was it.
