Yes, you're one of very few people who haven't experienced any bugs. It doesn't meant that bugs don't exist.
Keep in mind that almost all PC players on this forum are using the unofficial patch, so bug reports are now less frequent than they used to be. However, if you take a look at the list of bugs fixed in USKP, you'll realize how bug-ridden Skyrim is.
I suggest you visit Solitude and pick up Roggvir's amulet before talking to Svari. Guaranteed bug at the end of the quest. You could also try to collect every book you find in chests in dungeons, one of them will surely turn out to be a quest item you won't be able to return to the questgiver.
I am referring to unpatched bugs. Also it sems like a lot of the current bugs are easily avoided if you have played a lot of bethesda games and use some common sense. If something looks to be part of a quest but you haven't started that quest don't mess with it etc.
If I go to a dungeon and find a book, why on Nirn would it be common sense not to pick it up? Have you ever done Blood on Ice? This quest is so bug-ridden that virtually all of us have at least one character who's never been able to complete it. Can we fix Quick Reflexes with common sense?
