At $3.99 this was an instant buy for me until the App Store told me I couldn't. I think the venn diagram between HN users and those holding off on Tahoe is probably a pretty big overlap. ;-)
I was in Las Vegas when this happened, though we had no idea that day that this is what was happening. My wife and I went to get tickets to the Titanic exhibit at the Luxor and they said "our computers systems are down, we can only take cash". I had cash, and they sold us the tickets for extremely cheap.
Long story short, I've always felt like I stole from the casino that day too! :-)
