@Scrbblchick -- I know what you mean. A standard smartphone has enough computing power to fly the Space Shuttle. There's a thought for you!
I thought nothing could beat the CD, and then they came out with re-writeable CDs. Only you had to have a special program to "burn" the CDs. Now, of course, it's drag and drop. And then there were DVDs, and re-writeable DVDs. Now we have thumb drives that have 100 GB capacity. Oh, to have had one when I had my old computer and needed to back it up to something besides a bunch of 3-inch floppies! Of course, I remember when having a 10 GB hard drive was a big deal. Now my laptop carries 456 GB. I'll never use all that space.
