Toshiba builds 100GB iPod-sized Disk Drive

The jump from 80gb to 100gb is 20%
i did the math backwards to simply for some simple minded people.

wow... I had no idea TUAW readers were so bad at math.. must be all the movies and photo albums and FUN stuff they do.. don't have time to keep up in their math class. I bet this kind of thing would never happen in the pie-chart making PC forums...

Math Pedant, you clearly are not in fact concerned with minor details as a true pedant would be as 20/80 is in fact 1/4, not 4. I, myself, am rather pedantic in general and so could not let you go un-chided for that silliness.

And before anyone gets their Justin Long boxers in a knot, I'm only poking fun. No really harm intended.

Actually Billy...

the 20GB difference is a 25% increase over the current 80GB hard drives:

20GB / 80GB = 1/4 (ratio of difference in relation to current) also known as .25 or 25%

20/80 = 4.
So it's a 25% increase. A 20% increase would only get you to 96. 80 is the denominator, not 100. If you started with 100 and went to 80, you'd have a 20% decrease, not 25%. Otherwise, going from 100 to 0 would involve a 125% decrease, which is still not technically possible.

You mean 20% jump (100-80=20, there is 20% difference). But very awesome! I've always said my next iPod will be 100GB. It's about time I update from my 20GB 4th Gen. iPod. I hope it'll be ready by march when I get the extra birthday money.
