For example, John asked his techie friends (a list I'm apparently on) about a tablet PC today. Here's his wish list:
One that has at least one USB port and a CD/DVD drive. One that has at least a few gigs of RAM. One with a modern Intel board (i5, i5 etc). One with a at least 1/2 a Tera bite memory (hard drive - solid state etc). The ipad is cute, but without these features I can't use it.In my time, (visualize the weathered porch as I tip my rocker back and gently gum a stalk of some grass as I push my straw hat back)... In my time, I've seen the USB port render serial (9 pin and 25 pin), keyboard, mouse, parallel and SCSI ports all irrelevant. I won't put the old edge connectors into this realm as they weren't really part of the mainstream PC world, but there were things like firewire and proprietary cards for ZIP drives at one time that all died quietly in a neglected corner of my basement.
Storage media keep rising and dying faster than we even realize. Not to bore you with RLL, MFM, IDE, SATA, and all the other acronyms for hard drive controllers (whoops, too late), but think about John's request for 500 GB hard drive. He's even using the word Terabyte, if only looking for half of one (a Terabyte being the next big number above a Gigabyte). The days of measuring things in Megabytes or Kilobytes are so far gone it ages me to even talk about them, so let's not even think about floppy drives.
And then there's optical media -- CDs and DVDs are disappearing like the unmentionable 3 1/2" floppies. I almost never use optical media anymore. I watch movies on Netflix and install software over the Internet... Heck, when we got that new system for Purnima in the office, she installed Adobe CS over the Internet, and it installed amazingly fast for one of the biggest programs out there.
But some things never seem to die. I just noticed an image file with a created date stamp of 2000-06-19 the other day -- if that image was a person, it would be heading into 6th grade... And what's more interesting is that the recordings of 100 years ago are being converted to digital formats and are suddenly alive again, even though no one has a 78rpm record player or a phonogram that plays wax cylinders.
Everything changes, everything dies, but not everything is lost. To the contrary, as things keep changing, we keep finding more knowledge, art, and ideas. It's not dead, it's just moving really fast.
