Dyson vacuum — cordless, electric rechargeable — this thing is amazing!
Also thank god clothes are “reusable”!
Issues with digital cameras with non interchangeable lenses — you cannot replace the sensor. Or if any part of it breaks, the whole thing goes kaput. For example, my extreme annoyance that after my Ricoh 3 or 3x breaks, the whole thing is pretty much unusable.
Also the big issue with iPad; essentially the iPad is not really reusable beyond 2 to 3 years. Yours got an upgrade or replace it sooner or later.
The very good thing a Tesla — the body style will pretty much not change much, even a few decades from now. And also the outside is because it is electric, just recharge it! And definitely reusable.
