Why not? I think I'd've taken it.
I was curious to see how it would play out and thought I will take it later (I checked in on my cell and generally don't like doing financial transactions on mobile). Of course three hours later when I did go on my PC, the upgrade standby list was 29 long - I was surprisingly still 2nd on the upgrade list as had been at 24h - however, the two available F seats were gone so I suppose people did jump on the offer...
