Must be the abandon-GAW-week...

I too butchered my hashlets just yesterday. Having gotten in relatively early, I easily reached ROI and turned in some from butchering my overpriced primes and a handful of zens.  

The whole prime-buyback clusterfuck was both hilarious and frightening to observe. First they promised a complete buyback. Then it reverted into a partial-buyback with mining profits deducted.
Then finally they implemented some sort of limited buyback scheme just before they opened the prime market. After this event, the buyback stopped and apparently they even introduced "cancel buyback"-button.  

Smart bastards. Much more profitable to take 5% + 5% cuts form the open market, rather than taking a loss while buying back their own hashlets.

Thank gawd the prime hype is still going strong. I doubt I could have gotten out with my profits as easily after a few weeks, once people start questioning the project primes gawsumness.
After that point, nobody will fork out over 40$ for a hashlet, whose value lies solely in the hype and speculation.
