Your body needs the energy to properly digest food. So to get the most out of the nutrients you consume and your workout, eat before exercising or 30 mins after fruit, two hours after veggies, three hours after grains four hours after meats and poultry.
So it's not a matter of value, it's a matter of what you need it to hold. And a matter of affordability. The movies will be the biggest space hog. So if you only put the movie you want to watch next on the iPod touch, so one (or two) movies at any given time, you will have more than enough space with either 16 or 32 GB. People watch movies once (twice if it's really good); they do not watch a movie over and over again like listening to songs.
Next, take 1,000 kilobytes, toss âem in a bucket, and you end up with a megabyte (MB)âand now weâre finally getting somewhere. With a single megabyte of memory, you can store about three average-size webpagesâor one quarter of a your average, ten-megapixel digital photo. A typical song from iTunes, meanwhile, weighs in at about five MB, while the Facebook app for iPhone takes about 10 MB of storage.
