I already bought a BN nook .. it's one of the best ebook reader using e-Ink, the new iPAD will be around 2500 QAR and won't be available here in doha till may or juin 2010.
if you are interested , I'm selling my nook :

My problem with it is that it's not showing Arabic properly. but if you are using only english book .. this is the best .

you can buy ebook or put your PDF on it.
check BN website for more information.
