Well, personally...
"I have a 12W LED that's supposedly equivalent to a 60W bulb, but is not noticeably darker than a 100W incandescent bulb and is certainly brighter than the sunlight through the window. If someone decided that they wanted the room to be lit with 5 of these to make the room painfully bright then that still only adds up to 60 W, 40% less than a single 100W bulb."
I've been waiting ages for cheap LEDs that I can string along behind the picture-rail in my living room in order to have an uplit ceiling with subtle differences in colour and intensity based on mood and time of day. I also have a fairly long L-shaped hall which has funny patterns of light and dark because of where the single light is located.
LEDs will probably end up being used in long strips rather than in single "bulbs".
Think the end of the "lamp post" and instead a great big row of LEDs stretching along the buildings at the side of the street casting uniform light on the pavement rather than a series of amber cones will dull patches in between.
Think aeroplane/cinema-aisle floor-lighting in most offices and public buildings, and think of that being considered a health and safety requirement, hence always on. Think of door-handles that glow constantly in a soft blue, and these being required by health and safety. Think of a stair that has all its edges lit up, and again think about how that ties in with health and safety.
Think of garden ornaments (although they'll probably have their own solar power).
Think of bicycles and motor vehicles with sidelights for added peace-of-mind.
Think of small lights inside all of your kitchen cupboards and appliances, rather than just the fridge and the oven.
Think of a keyboard with LEDs under each key so that the letter glows.
Think of beds with a string of LEDs in the headboard for reading.
Think of some other things that I'm not going to mention cos they might be patentable....
