BusinessWeek has a slideshow revealing new electronic devices that a consumer could use to enhance (or complicate) certain aspects of daily life. Among these is the very promising Sunlight Direct System, which I discussed back on September 5, 2006. Others, such as the Lawnbott ($2500), cost far more than the low-tech solution of hiring people to mow your lawn for the entire expected life of the device, ensuring that mass-market adoption is at least 4-5 years away.
All of this is a very strong and predictable manifestation of The Impact of Computing, which mandates that entirely new categories of consumer electronics appear at regular intervals, and that they subsequently become cheaper yet more powerful at a consistent rate each year. Let us observe each of these functional categories, and the rate of price declines/feature enhancements that they experience.
