This is funny but if you believe in the research results, this might give you an eerie feeling. A research was done recently to see whether inserting more and more songs into an iPod or MP3 players make them actually heavy. The results turned out to be shocking.

The results showed that iPods, iPhones and MP3 players get a ‘little’ heavy upon installing files in them. The tests were done by weighing an empty iPod and a full one. The difference turned out to be 0.4 grams. Upon filling 3500 songs in a 16GB iPhone, it weighed 133.6 grams compared to an empty iPhone which weighed 133.2 grams. Professor Roger Banks quoted that this was for the first time a digital data has been measured in a real world measuring unit. We all know it is made up of 0s and 1s but the ratio of ones to zeros actually seems to make a difference. Further research is being carried on to ascertain whether different file formats weigh differently with the same file size. [via]
