"As for longevity, you can expect to get about 8,000 turns before it caves from exhaustion, and if your eyes tire, the unit can double as an MP3 player."
I didnt understand this longevity part... How come just 8000 turns ? You meaning turning on and off or page turns ? Please be more specific cos this the first time that I actually considered in buying one of those eReaders...
8000 page turns is the battery life estimate. Basicly this thing doesn't use any juice while your looking at a page, it only uses power when you flip to a new one. Could you imagine how long you could go without charging?
Well there is good news and bad news on battery life. In the real world, 8000 turns basically means you can read an entire book on a single charge. In comparison, if you have a heavy day of reading on a PDA-type (lcd) device you will run out of juice during the day and definitely won't be able to finish the book.
However, the 8000 page turns is a manufacturer's rating and like many such figures it overstates the number for various reasons. 1) e-ink typically takes two "page-turns" to turn a page. When you turn a page it first flashes/refreshes the screen to wipe out the old text, and then it writes the new screen. This flashing refresh can be turned off, but (if you look closely) you will see some specs from the previous page if it is off. It appears that the 8000 rating is done with the flashing refresh off.
2) In theory, the device only needs power for a page turn, because the screen only needs power when it refreshes. This is because the e-ink screen only needs power to 'paint' the image. Once it is displayed no power is needed. In reality, however, the processor may still be running and it may still need power.
3) Depending on font-size and the comparable book size don't assume that one e-ink page is equal to one paper page. This is a real problem for those looking to read pdf's on a six inch device if those pdf's are static images (ie non-reflowable). It's really not reasonable to do.
Bottom line is that the battery life is great, and if you recharge it daily or even every other day you will be in great shape -- much better than with competing technologies. But, don't assume it lets you see 8000 pages.
the Nook Color proved it was an undercover tablet all along, Barnes and Noble has hit back with this latest Nook as proof of its focus on one thing: reading.

@Micheal
I do fine just charging my Sony Reader just once a week. Doing it daily would be rather excessive IMO.
