The 7500 number also tends to assume that you don't switch books, make notes, read the dictionary and so on. Every time you access the dictionary, move through menus, or really do anything that updates the screen without turning the page eats into your page count. So all those additional features take away from reading.

There is also a residual drain from the CPU/RAM being powered that eats into the page count over time, no matter what you do, which can lower the page count the longer you leave it asleep (Sony's test of 7500 pages doesn't let it sit for very long, so the CPU is not really as big of a factor in battery life as it becomes over the period of a week or two).

I will agree that the battery meters really don't seem all that accurate during the week week of ownership, especially on the 600/900s where you have the touch screen.

EDIT: Also, 7500 pages is 7500 page flips of the device, not 7500 ePub pages, which is a bit confusing.
