If I was a malicious attacker with 51%, I'd prevent everyone's transactions from happening and ask for a significant ransom. Once the ransom is paid, then I'd resume normal activity. And maybe rinse and repeat a little while later.
That's the only way I can see that I'd be potentially profitable without being traceable. I can't imagine a double-spend actually working. I'd probably end up getting caught and going to jail. It'd be hard to buy ANY physical good without leaving some sort of trail. And asking for higher transaction fees might work, but it'd be the lower-profit option, I believe.
Now, if I was a reasonable person with 51%, I'd just mine the heck out of Bitcoins and have a nice pile of them to do whatever I want with. Seriously, if you're money-motivated, and have 51%, THAT is the best option. It won't reduce confidence in Bitcoin (and thus your Bitcoin net worth), and it would continue to be profitable long into the future (whereas a double-spend or ransom attack would only be profitable in the short term).
Basically, I would completely eliminate the possibility of a 51% attack happening. I don't see why any reasonable person would do it. It would make them less money than simply mining with that hashing power.

I see it pretty much the way you do. That does still leave us with an entity that is not motivated by money and simply wanted to destroy bitcoin.

I'm trying to visualize what this all means. Soon the 7200 bitcoins per day max will be halved to 3600.
So now we have 3600 bitcoins spread out among...what would people guess...200TH/s once ASIC hits? 2,000TH/s?
aye, it's really hard to speculate now and comes down to just how much miners are willing to spend to buy asics. The preorders currently put the new hash rate at maybe 45TH by reward halving(much citation needed still). And will be largely influenced by how well the release goes and whether that encourages more miners to buy equipment or not. BFL won't get to 2000TH/s any time soon. If you think about it, using the current SC ASICs that would be 2000 MiniRigs or 50,000 singles. Given the little we know about BFL's production and assuming that the new singles/minirigs take as long to produce as the old ones, how long do you think it will take to get 50,000 singles out the door? Of course, the $70M that would bring in at current prices finance quite the expansion. We know via Bit-Pay that they got at least a quarter million dollars yesterday alone. http://www.marketwatch.com/story/bitpay-shatters-record-for-bitcoin-payment-processing-2012-06-26That buys 8.3 minirigs or 8.3 Terahashes. Do you think they'll be able to ship out 8.3TH/s worth of gear in one day? It's a good question given their track record. That said, in the past they were new at this and selling to a skeptical client base. I assume if they are smart enough to build and ASIC they are smart enough to solve their supply chain bottlenecks.

Technically... the rest of them. But really just a few times the normal amount in a day will send difficulty skyrocketing and bring it back to the average amount quickly.

This is true. I should have concluded my post with "I would completely eliminate the possibility of a 51% attack happening by any profit-motivated malicious attacker." 1. Take a short position on BTC. 2. Destroy Bitcoin with a 51% attack. 3. Profit.
