no actual data here: no power (Watts) provided for the netbook to enable a fair comparison.
It's great that it did not become ewaste, and a computer you have is better than one you don't have, but people likely shouldn't pick up old netbooks over something like a pi.
I agree. The machine is remote so I don't have it on hand, but I believe the stock AC adapter is rated for 40 watts according to a search online. However, I haven't recently plugged it into my Kill-A-Watt to see the actual draw, especially since I run it at half frequency. I'll bring it with me next time I'm out there for an upgrade to see what it actually pulls. :)
