My wife is starting her 2nd career (after 25 years as a Pastry Chef). She's in nursing school and has HUGE medical books. I picked her up a Kindle at Christmas with the idea of replacing them.
Well, it's a yes-and-no solution. Not all her books are online yet. Also, a lot of her physiology lab books rotate every semester. One of them, a particuarly large dissection manual, costs $300 used. On the Kindle the same thing costs $192. Some savings...on one hand I am aghast at the cost, but as a business owner I understand about making a profit...so let's drop that there.
Anyway...when we downloaded the manual I was amazed it was edited.??!!?? There txt was basically the same but the graphics had been reduced in resolution. At the time I felt that textbooks and Kindle's weren't ready for prime time (my observations..YMMV). When the iPad came out I said "Aha!" a e-reader with a quality screen....THIS is what the txt book world needs.
Unfortunatly for my wife...the first iPad is mine

We don't splurge much but we do take turns...and it's my turn!!
Can't wait for Saturday...
