Ok, I was wondering what the actual hard drive size is of all the current iPods. I know with normal hard drives they round them up a bit, is it the same case for the iPods? The reason I am asking is cause I may be getting an iPod, not sure yet, but my music collection is over 5gb's and i get new CD's fairly often. Is the extra money really worth it for the 15gb? Is there anyone out there who baught a 10gb and later relized a 15gb would have been better? Thansk for all your advice in advance!
