I've never used those pens or shovels and have never seen them for sale. The point you're missing is that while they may - or may not - by more user-friendly, they may also be harder to make, or to store, or to transport, or whatever else. The original design is still the most popular by far because it's well-proven, as are rectangular doors, elasticised socks, T-shirts, coffee mugs, and even clocks with hands on them. There are many alternatives, but none of them are functionally better than the standard. And that is the key: form following function, function meaning the whole working life of a thing and not just the single intended purpose. There's no reason Land Rover can't produce a workhorse Defender, (or a replacement), as well as the lastest fancy-pants Range Rover. The market is there - the company has not tackled it.
And if you want to have an interesting discussion, leave the personal stuff out about how some of us need to move on or whatever. That's our business.
At any given point in time, somewhere in the world someone is working on a Land-Rover.
