My grandfather is 85. He has about one hundred cassette tapes with music he loves. He no longer has a cassette player. He wants to buy one he saw for $10.00. Using your logic, I should inform him that cassette technology is DEAD. No one I know uses cassettes anymore, and because of that, he shouldn't want to either. There is far better technology, so even if there is a good and inexpensive solution for him, he shouldn't bother with it because I personally don't listen to music on cassettes. Genius.
Nice attempt, but you faltered a little with execution...something detrimental to your "calling out" of a senior member. Let's address this...the argument at hand would be like having new cars support tape decks because your grandfather still had so many, and having negative opinions of a new vehicle because it came with all the bells and whistles of todays technology, but did not support cassette tapes.
10 years from now, there will be people clamoring for the support for CD's in a car...but even now, using a hard disc to play music is near it's life end. Your argument is not uncommon, but it's pointless...technology moves too fast to get stuck on the kinds of things that were popular before the kinds of smart phones, tablets and computers we use today even existed. Soon, hard drives will become obsolete, but you'll still have those who just cant let go of the fact that they think they need an actual hard disk to store their stuff.
Move on people...if there is a device that offers flash that works well for you right now, go use it...but don't expect the rest of the world who have moved on to be stuck with it, i don't need all the little crap required to support flash taking up space on my new generation phone, just like i don't need a giant, ugly cassette player staring me in the face on my dashboard.
