I've got a kindle but it doesn't stop me buying physical books. It does mean I buy fewer physical books, which is good because I have more space and not as much stuff to dust.
Other pros of kindles:
You can highlight stuff in the kindle easily so you can look it up later
You can search for keywords so it's easier to find stuff
You can change the font size
You can read super-embarrassing books and nobody will be any the wiser
Not as good:
Easy to lose
You can't ostentatiously show off how clever you are with the highly visible contents of your bookcase
You can't sort your kindle books by number of pages, wtf
I put a cover on mine and it got really stinky and I had to put it in the washing machine and it got ruined :( (the cover, i mean, not the kindle. though if i'd put the kindle in the wash that would also have been ruined. and so would a book, if i tried washing one of those)
