what about that textbook pdf rental scam going on on campus eh? i just take pics of each page and digitize it and then return the book. hell no i won't get ripped off. the joke's on you, mr. 219th edition of the same subject rehashed on different pages. textbooks are actually one of the nicest scams running the campus today. they just change pages around. i did this starting back in mid 2000s in college with a cheapo digital camera. shuffling out a few hundred bucks to use a book for a few months was not worth it. we never ever used an entire book either. and now all material is online anyway. it's not like knowledge is a secret like it was in the 80s or before. everything fits onto a cellphone.
also, the digital vs. hard copy issue - if you live in new york city (i am in brooklyn in good ol' scamriffic brighton beach with the russian mafia laymen), you will need space and books take up space, invite tons of bugs of all kinds, and are awful to pack when you have to move (uh, yes, you will be moving often). digital is incredibly superior and especially more so since you can make multiple backups of the jpg files or pdf's. last i read a week or so ago, google just made its cloud data service unlimited. you can store as much as you like. this is beyond thumb drives and hard drive backups.
