Amazing is hardly the word for it.
Everything is fun about this game. I chose a character that dabbles in fighting, magic, and stealth. I can't believe how flawlessly the game allows for such openness. Even the mini-games such as lockpicking are pretty engrossing. I found myself going to every person I came across and played the speechcraft mini-game (I think I'm getting good at it too!!).
I'm not even running this game on a powerful PC (2.4 gHz, 1.2 Gig RAM, ATI Radeon 9800 128MB) and I can put the draw distance to maximum. The video options allow for a happy medium of video quality and framerate success.
The bottom line is if you have any interest in RPGs at all or if you've never played them and think this might be even remotely entertaining, I would recommend this game for you. It's beautiful to look at, the gameplay is top-notch, the story is interesting, and the possibilities are endless.
Get up, go to the store, buy the game, come home, install it, and kiss your boredom goodbye.
