After 22 years of insightful and important commentary on consumer technology, Walt Mossberg has written his final column for The Wall Street Journal and its All Things D tech blog. Included among his dozen are Windows 95, the Palm Pilot, Googles search engine, and the iPhone. The products chosen werent necessarily big sellers — his first choice on his chronological list, the Newton MessagePad, was an outright flop — but Mossberg believes each of his selections improved ease of use and added value for the average consumer. His tastes and criteria have led to a few arguably strange selections, such as 1997s Palm Pilot included in place of possibly more deserving candidates in Sonys PlayStation or Netflix, but most of his choices were bona-fide game changers.
