The article discusses charging the iPad and iPhone - not the iPad and iPod.

If Apple says it's fine, then it's fine. I use my iPad's brick to charge my iPod and don't anticipate any problems.
 
I wouldn't use the iPad charger to charge my ipod. Cause the power output is bigger. Normally is 5W but for iPad is 10W. This may cause damages to the battery in the long run.

Not so sure about this but i wouldn't take a risk 🙂
I have tried charging my itouch with ipad charger before, but the charging didn't start. So yeah I chose not to. 🙂
 
iPad Charger works just fine

I have been using it to charge my nano for the last year and it works fine. Nothing indicates that there is a problem.
 
You could use a 1000000 watt adapter, but the iPod will only pull its max amount (5 watts I think) anyone who says using more watts is beneficial for the ipod/iphone has no idea what they're talking about.
 
Universal question.

Some prefers to use Iphone charger for ipod and some dont mind as long as it charged. Tell you what, get another adaptor for $19 (the one that sold seperately without cable) and have a great night sleep without worry.
