Yes, I've seen bugs in almost every game I've played.
However, Skyrim has game breaking issues that will likely never be resolved. This is unacceptable.
Although you gave the somewhat snarky reply (I quote verbatim) "because surely your lack of problems is indicative of everyone else" already - I have yet to experience the purple texture bug, or any other significant bug at all, in 109 hours of PC gameplay. This on a PC that very commonly got purple textures in Oblivion, on lower settings. Specs between required and recommended.
While I may not be indicative of the majority, I and people like me may very well may be MORE indicative than your experience - people don't come onto a game's forums to state that they're bug-free. At the very least the presence of bug-free PC players tells me that game breaking graphical bugs and crashes are hardware specific. THAT can be hard to test for.
