Found the character dev very amusing. For example, when you have 100 on pickpoket, you can actually steal armour from people while they are wearing it! (with the perk, of course)
-And if you steal armour from town guards, they will then walk around in their undies from then on!!! _Funny
Of course, it did take me ages to get pickpoket skill to 100, but as I had completed all the quests in the game, I had time to waste in such minor stuff.
Oh, and I also have destruction, one handed, and heavy armour on level 100.
As a result, there is nothing on skyrim that can kill me.
Bads: many shouts are totally useless.
