2: They where tracking what kids where doing on these tablets... seems fishy and somewhat illegal, especially without consent. and if the consent was in english on first startup. I think it's rather invalid.
3: if they where tracking them there must have been some sort of internet on them, heck they're pretty useless without internet. so how do they know they didn't get any help ?
There's a lot missing from this story and a lot that seems fishy.
I took the bit about the SD card with tracking software to mean that the software stored information on the SD card about what they had been doing. Then all they needed to do was retrieve the SD card to work out what they had been up to
If they had figured out how to turn on the camera I would have though the kids had been smart enough to "Hack" the tablet and discover this data too
Personally I think we should build a call center in these villages, give the kids a PC and a phone each and let them do tech support. Think of the cost savings
