My current private laptop ist 7 years old and still running fine. It's some dell laptop and I suppose it will fall apart at some point but so far I don't see why I would replace it. I wouldn't mind it lasting another 10 years.

Same for mice. I'd certainly use a mouse for 10+ years if it's good enough. I've invested in a quite expensive ergonomic, mechanical keyboard and I have a very old mechanical cherry keyboard at work and I do expect them to last forever.

If you don't need the latest sh*t (touch bars and what not) you'll probably be fine with current characteristics of laptops for quite a few years.

I use a mechanical keyboard at home, but I won't use it at work as it would drive my fellow cube farm dwellers nuts. Is your keyboard a silent click one?

Cherry MX Brown... it's not that they are silent but nobody complained, yet. Never even heard a comment about it, really.
