The real problem with tablets

You know how sometimes you can have read the same book a hundred times, then you get a different copy and reading the same book in a different font will make you notice things you hadn't or give the whole thing a substantially different feel?  What if you go all e-reader doodad and then they won't let you change the font?  Maybe they let you change the font/size and all that stuff already; I'll never know, thank Christ.  And this is even before "they" start gathering up all copies of paper books and destroying them then deleting the availability off their platforms.
