I bought a Galaxy Note earlier in the year and started buying novels and such on the Kindle app. A few days ago I bought two novels as eBooks that I already own in paperback format. (The reason being that I moved house earlier in the year and have less space so physical books are somewhat limiting. And the paperbacks are in boxes in storage.)
In the same way, I've also got on Steam at several times the last couple of years and bought (usually at a huge discount) some games that I also already own. Some of these were updated for modern PCs, but not all. Again, the reasoning was that it was too hard to go searching for the old disks, especially since some of the games were under $5.
Now with the twentieth anniversary of Doom, I feel tempted to hit Steam and buy that.
Of course, with Doom that was never on CD, that was a bunch of floppies and not many modern computers have those any more.
But this has got me wondering, what do you do?
Are you happy to buy a game, or any product for that matter, more than once; or are you someone who steadfastly refuses to buy anything a second time (unless it's physically broken?)
