>> and lets face it, these guys aren't soldering the components, it's fitting together parts into the ipad casing. so you can probably build 10, 20, 30 a day? once you get used to it, I think 20 a day should be easy. so that's quite a good wage then, by comparison.
I would be very surprised if they are assembling a complete iPad. They will be perhaps 1 of (say) 25 cogs in a wheel. Assuming all 25 cogs are the same size, 20 a day would mean repeating their task 500. Sounds reasonable. $160/day seems like a reasonable wage.
The only way to come to this figure is to make a lot of assumptions - as many others have pointed out, the article is lacking on details. But even without the efficiencies of a production line, I reckon I could build 20 iPads/day if I were doing it day in day out (and I'm a stubby fingered westerner). It would be one every 30 minutes on a ten hour shift.
Ofcourse when they say $8 per iPad per worker does that equal take home pay per assembly worker? Or are there overheads which need to be paid out of that $8 first e.g. power costs, admin/support/cleaning staff, robot maintenance... - so, tell us how much per hour the assembly workers are getting, and maybe then we can comment on it.
