Robert C please tell us why your e-readers don't last. Do they break from rough usage? Do they just stop holding a charge? Do the screens stop working properly? Are there software problems? Let us know. I don't know anybody with an e-reader.
I would be extremely angry if I paid $100 or more for an e-reader that died after reading only ten to twenty books in a year.
I have had my sony PSRT-1 ereader for 2 years now, have read countless books on it, lugged it around on holidays and its still working like a new one. So durability isnt a issue (for me at least it isnt)
Besides, i have a backup of all my ebooks on my desktop pc, my laptop and on an external hdd. So in case it does break i'll just buy a new one and copy all the books again and be done with it in 5 minutes.
Another one which I don't think has been mentioned here is banking. We can do the vast majority of our banking online now. Our pay is automatically deposited in our bank accounts ... long gone are the days of "paycheques". Our bills are paid online. We can set up accounts, rearrange accounts, transfer money between accounts, apply for loans online .... just about anything we need can be done online.
For most things there's no need to leave the house, let alone get into a car.
And if we happen to need cash for occasional things, we can ask for cash back when we go shopping in just about any store.
