I'm not bored in the least. In fact, I'm overwhelmed because there is so much to do.
I could spend hours merely:
-exploring unmarked terrain on map
-organizing/decorating my house
-walking around interacting with people
I get so easily sidetracked in this game, it's ridiculous.
I've been playing non-stop (to the point of being completely unhealthy) and I still haven't finished the main quest

I also am yet to experience:
-Thieves Guild
-Companions
-Dark Brotherhood
-Imperial/Stormcloak
-Nearly every "miscellaneous" quest
It's hard to explain exactly where all my time went. I am pretty unfocused when it comes to quests, yet somehow in my Skyrim experience, it feels like A LOT has happened.
I've seen my character grow in spirit and in battle. I've endured the loss of Lydia and three black stallions. I've trekked through swamps and forests and to the peak of snow-capped mountains. SO MUCH has happened, yet... so little has happened. It's a beautiful thing if you ask me.
