"... (flickr) A website that does little besides arranging "img" elements is fundamentally lame ..."
That isn't an accurate description of what flickr does. The kinds of problems they work on are a lot more complicated than arranging images.

One of the most ubiquitous inventions I've seen develop in my lifetime is luggage on wheels. The technology is trivial (it's a combination of two simple things that have existed for centuries) but somehow it didn't get invented until the late '80s/early '90s. Now you wouldn't buy a suitcase without it, and it makes travel infinitely more pleasant.
This does require being able to travel quite light though - most of my trips are 1 week or less at a conference so I only take clothes, laptop and assorted chargers.
