. Macintosh Portable: 1989 with lead battery - a 16lbs monster with a 10hrs battery performance. $6.500 was too much for cost-conscious consumers
. Mac-TV: 1993, an attempt of bundling computer and TV in a same box. 10.000 pieces sold - I would think that it was a success
. 20th Anniversary Mac: 1997 with a $10K price tag. Dropped to about $2K with no taker, but it has been a classic on Ebay commanding quite a high price.
. QuickTake: 1994 Digital Camera, developed in conjunction with Kodak and Fuji. With lousy pic quality and work only with Mac systems, they went the wayside of a mis-cue development
. Newton: 1993 as Notice block and Calendar manager. Too slow and too heavy, it was ditched in 1998
. Mac Cube: 2000. With no hindsight into an expandable system and too expensive (what else is new with Apple dings), only 150K pieces were being sold.
Looking back we see here a pattern that Apple believes in its ideas and willing to go back and rewrite the specs yet keeping the products focused - that is genius in itself for any successful companies
