Well,I think it's obvious that there is a change for sure!
Most e-ink readers have a battery life that completely outperform any notebook!
This means you can read longer times non-stop.
The reader is way smaller and lighter, this means you can put it in the pocket of your jacket, and take it anywhere without problems.
Also, you can take it with you to read in home places like bed, toilet etc, without the discomfort of a laptop/desktop's size,wheight, or having to plug it into a wall and be dependent on where the cable can connect.

Any person using a e-ink reader has said the same comment, that it is less straining to the eyes; but I believe in pure sunlight the reverse is true.
If you have a laptop with a reasonable backlight,that is much better to use in the open sun than a reader.
The white page,just like with a book, can really burn in your eyes with long use in sunlight (you'll see green spots after reading outside).
This leads me to believe the reader is the best device out there to read in shadows outside, or in inside environments.
Reading is nearly 90% identical to reading a book, even in low-light environments like eg: in bed with a nightstand (light) on should be possible...

PDF's read slower than text, and you can get your best experience of the resolution by comparing to set your laptop to a resolution of 800x600 pix.
If your drivers support to not stretch out the image on your laptop screen, you'll have about the best comparison (about 20 by 15cm screensize?)
You'll see you can only read most pdf's in landscape mode. Sony's reader supports pdf upto 120% zoom, which basically should be to zoom a normal pdf book, without the white borders around it.

I found manga/comic books works ok, and is readable in landscape, however in portrait mode most anime with small to regular fontsize will become unreadable.
With landscape I seem to notice that the screen refresh rate is a big issue, since you can read only about 1/3th of an A4 page, then PgDn, and have some overlapping piece of the book.
Those who read comic books fast, will notice it is less pleasant to do it on a reader, though not impossible.

Lit and other specified e-reader formats are the same as books, more designed to compress textbooks than comic books, though some formats support pictures.
The format generally automatically starts a new line of text when the old line is too big to fit the screen.
One con I find, is that often many formats only support 1 font type, though some do support inverted text, Bold text, or larger fonts (I don't know if any supports Underscore text)

So all of the above can be said about most e-book readers, not only the BeBook since that's common for most readers.

On the BeBook which supports 4 greyscales you'll have slightly more grainy pictures, since the only colors it supports is Black, dark grey, light grey and white.
It tries to compensate the different colors by rendering (meaning rastering darker and lighter greys), to get a color inbetween the 4 colors.
A sony reader is a bit more refined there, but in essence does the same thing with it's 8 grey tints.
