Let's not call it hoarding. Let's call it long-term technology. Let's call it extended depreciation. Let's call it extreme recycling. We all have things we don't use but can't let go. It might be irrational, but in limited amounts hanging on to a few things might not be so bad.
We live our life, and it's reasonable to save a few items to help us remember special times or periods. But the item needs to support good memories.
The item must be out and visible, not hidden away at the bottom of the garage. Garage items aren't helping anyone. If you don't want to see it, you don't want to keep it.
The item must look and function mostly as it originally did. Broken items produce less positive memories.
The item must represent something tangible that you can talk about. You're not just keeping for some unknown reason.
The item must be a single item, not 100 duplicate items. You want the memories, and one item will accomplish that.
You must not fool yourself over the antiques and collectibles value of the item in the future.
So save a few things for your life's personality collection. This is healthy. Older technology can sometimes be a attractive and interesting to your guests, as my Apple Macintosh is.
