I've been having a lot of fun exploring the southwestern wastelands the last few days, but there have been a fair number of noticeable bugs.  Crashes to desktop are fairly common (for me, they seem to get much worse when I'm near some body of water), and there are a number of times where quests or conversation triggers don't quite work properly.  I haven't experienced anything game-breaking yet, which has kept me pretty positive about the game.  I think it's pretty typical Obsidian: great story, poor quality control. 
 
I've attached a few screenshots below showing some of the lesser bugs I've come across in Fallout.  None of these are a big deal, but I thought they were interesting as I made my way across the wasteland.

Part of me wants to get this game on PC (have it on 360 as well) just so I can take screenshots of this kind of stuff.
 
And the mods.

The more I see of New Vegas, the more I want to play it despite the bugs.  Have you seen the head spinning bug?  
 
I've heard rumors of some others, like a mailbox being assigned as a radscorpion, but I haven't seen any evidence.  There was one really odd one with a corrupted save that looks pretty freaky, but I haven't seen that one duplicated anywhere.
 
I don't understand Obsidian shooting themselves in the foot all the time.  They would be revolutionary if they managed to put out more reliable code.  It's odd, but Bethsoft's reputation for bugs is so prominent now that when a new Elder Scrolls comes out, few seem bothered by the bugs anymore.  Like it's part of the equation.  With Obsidian they seem more geared to criticize.  Putting those two companies together seems like a weird recipe to me, but I hope the incumbent patches make things smoother.  I really want to see a Fallout game with this style and tone succeed.
