Digital Cameras Should be Forever

I have a Camedia Olympus D-400 Zoom digital Camera that I bought a few years ago from overstock.com for a few hundred dollars. It still works great. It now seems a little bigger and bulkier, since everyone else seems to either have cameras on thier sleek phones, or a much smaller, easier to carry version of a digital camera. I don't really see too many cameras anymore that have actual film in them. My camera uses a 32 Megabyte Olympus Smart Card to store the pictures. Its the only card I've used. The card has seen thousands of images come and go. The poor thing is getting worn out. I need a new one. My husband, on a thoughtful quest, decides to try and find one from Walmart or Sams Club. No such thing they say, as they snicker. They are obsolete. So, I check Google. I find an Olympus 128 MB SmartMedia Card. One reviewer on Amazon proclaims, "Rare Olympus Smart Card, not many of these older memory cards available for purchase". It seems if I want to use this camera for much longer, I better buy this card while I still can. Although there are other brands of SmartCards, they too are near obsolescence. If I don't get a card soon I realize, I will have to buy another camera to use. I spent $600 on this camera, which at the time, was a great deal. And $600 to me, is still a pretty good chunk of money. I don't like the idea of having to spend hundreds of dollars every few years just to keep doing what I've been doing all along. With computers, I've gotten used to the idea of having to replace one every few years. Computers started out that way, but I remember buying film cameras and keeping them for 20 or 30 years. Its not like suddenly the film types change, and you have to buy a new camera to accommodate it. Now that I think about it, I start to get really worried. It seems like anything we own anymore is controlled by a computer. And computers, by thier very nature, need to be upgraded every few years. So, does our future indicate we will have to replace every appliance and gadget we own every few years? I don't know about you, but I can't afford to do that. And I'm pretty sure it's not the greatest idea for our planet either. Come on computer geniuses, there's got to be another way!
