How often do you replace electronic and other appliances and devices with new ones?

Only when they break and aren't fixable or became incompatible with me or other devices/software.

I had to buy a vertical mouse two years ago because my hand got bad.

My smartphone from 2018 got suddenly extremely slow so I replaced it in 2022.

However I keep my Koss porta pro for many years and they have been repaired uncountable times. I'm thinking of getting a new pair.

When something breaks I get a new one

Replace when broken.

I keep them until they break or are no longer supported by the provider. I don't try to keep up with the latest things.

Just replaces my Pixel 3 with a Pixel 8..It was making mistakes..😷

Apple has a trade-in deal that looks attractive. If you buy a new iPhone 16 for example for $1600(?) and then trade it in for a new one again in 2 years time, they will give you $1400 in trade-in value for a new phone.

If you wait 4 years to trade, they will give you $1200 in trade-in value.

What this amounts to is about $100 per year in depreciation.

But if you waited 10 years to trade, they'll give you $50 for your old phone which represents $155 per year in depreciation.

The advantage of this buy and trade plan is that you'll always have an up to date phone and you'll incur the lowest rate of depreciation per year while doing that.

Buying and holding for years ends up costing a lot of money in depreciation and at the end of 10 years, you still have a 10 year old phone that is no longer compatible with upgrades from Apple.

My laptop is 9 years old and my phone is 2 1/2 years old. I would actually like to replace both of them.
