EDIT: Oh I give up with the table- 15 mins of fiddling in the dark and still no table! Anyone know of an easy way to go from Excel to here and still have a table? I've got to get on with "real" work now but I'm all ears on learning an easy way to display a table 
Thanks!
Thanks!Take a screenshot and post an image
Your math is probably right, profitability is marginal at the current rates. And the blade is not priced competitively, the "cupcakes" at $170 are <$0.5 per KH/s, the blade is more than that, unless it overclocks like crazy.
Same chips are used so you can do the math regarding OC'ing.
Personally I would have thought the blade would be a bit cheaper because the components used are costing significantly less than with the 'pods'.
Less heatsinks, less fans, less pcb, etc.
What I meant regarding overclocking is that you can push these chips to 950-1000 MHz with a bit of a voltage tweak. Now if the blade had that option without soldering (e.g. a software adjustment, or at least a jumper) that would be a significant advantage.
