Repairability is a big part of my buying decision making.
I don't know what % of the population does this, but don't think I'm alone.
The higher the cost of the product, the more important for me.
I usually check for Ifixit tear-downs or simply if there are screws on the back.
Having a kid around the house teaches you real fast the value of being able to fix stuff!
And so far, in electrical stuff, 90% was really simple (worn out connector, bad solder that breaks, bad caps, bad power supply) and only 10 was "non instant fix" (IC's going awol) that need a new sub assembly or a complete replacement.
My latest fix was cleaning the contacts and motor of a hoover, 150€ saved.
Today, I'm going to buy a waterproof Camcorder with my wife.
I'll be looking closely at the possibility of being able to change out the battery and if the power cord cord/USB/Card is proprietary.
If it's goofy non standard stuff that's going to aggravate me later, or make me drag a suitcase of cables on vacation, they can shove it up their corporate sphincter.
It must be able to work with the same charger as my Iphone, Canon Camera, wife's Nokia, Garmin GPS...
And be fixable, once the battery starts acting on me in a couple of years.
