Is it me?

Is it me, or does the reader actually get heavier when we add more books? I put in another 50 books today, and put 1,002 songs onto a memory card, and I'd swear that the 505 feels heavier...

Don't ones weight more than zeroes?

Get on your bathroom scale, with and without the ebook reader, and find out.

WDE.

It sounds like it was the songs you put on the memory card that did it. Remove the memory card and see if it feels any lighter.

I think songs weigh more than books . . . all those musical instruments; especially if you're in to heavy metal.

well that makes no sense. after all, the zero is so round and fat, while the one is thin as a rail. although i suppose mathematically all those skinny ones do add up.

i think a few grand pianos and some kettle drums must be pretty weighty too...

Actually, the initial state of erased flash memory cell is all ones - when writing actual bits, you can only go from 1 to 0, not the other way around. If you need to restore some 1s, you have to erase a complete block and write everything anew.

now that is very interesting. is there a technical reason making this more practical (the ones really are lighter !!

) or did they just make this decision arbitrarily ?

It seems to be related to the electrical properties of the components used for making flash memory cells. Wikipedia has some descriptions.

hm, interesting. i'm surprised to discover that while data can be written in individual bytes it can only be erased in blocks. technology is fascinating, isn't it...

it does seem to make sense though (although i could be extrapolating something which is not there) that the default state would be "on" (1) rather than "off" (0) ; so that means the individual byte begins in a receptive state, since to add data and change to zero, from what i've understood, it requires adding electrons (counter intuitive... add something to 1 to get zero... the description makes less sense than the process).

No, but when I add more books, *I* get heavier because I sit around and read them instead of moving my body.
