silly, the mp3s inside are much heavier than the electricity. so when you plug the ipod into the pc, it will automatically update your music and thus adding to ipods weigh.
the electricity has its own weigh as well. a full battery weighs 1/9 from 100 mp3s normal weight. i considered that mp3s are all 4mb and the battery is not charged above the overflow limit and is not leaking either.
i recommend an experiment: weight you ipod as it is now and weight it without mp3s or power in its batteries (you can do that by plcing your ipod in a bowl of water, you will get rid of all mp3s, electricity and ipod altogether)

Since the battery is sealed and the only connection is made via a power cable I don't think the mass can have changed. With no way for mass to be added it cannot increase in this case.
The energy content of the battery will have increased & there will have been consequent chemical changes - since the energy is stored chemically.
If you are being completly pedantic then the overall mass-energy will have increased by a tiny fraction (E=mc^2) but you would definitely not be able to notice this.
What other factors change when you notice the difference in weight? Is it usually the first time you pick up the i-pod in the day? Maybe you just forget how heavy it is :)

The way that a battery stores energy is (put in a simplistic way) by moving electrons from one half of the battery to the other. Whether it's charged or uncharged, the electrons are still inside the battery, and therefore it weighs the same.
Imagine it a bit like a sand-timer. When you turn it over you're giving the sand potential energy which it then releases as the sand falls down to the bottom. However the total weight of the sand-timer doesn't change.

Acharged and uncharged battery have the same MASS. However, the charged battery has more energy (stored in terms of bonds between atoms). Since some believe that energy and mass are both affected by gravity, then yes, charged battery may have more WEIGHT.
yet, this weight is so tiny that you cannot feel it.
and i won't even go into the weight of mp3s?!!

You must be imagining...a charged battery just means that the electrons are collected at one end of the battery, where an uncharged, has electrons uniformly distributed. So charged just means that there is a different physical configuration...just like moving furniture around the room..it doesnt change its weight.

I think you are simply imagining. Electricity has no direct mass, since what you see as an electric current is just a displacement of electrons from one place to another.

Technically E=MC^2 so if your i-pod is storing more energy then it IS heavier.
However the difference in weight is far too small for you to notice!

Interesting question! I don't think that electric charge has any kind of weight though. I'm sure some science boffin will prove me wrong though!

each electron weighs 9.109 x 10/|\ -31 kg

Errr... not likely.
