Released at the peak of Palm's powers, the m100 was intended to be a "PDA-for-beginners" that cost less money (only $150!) and had smaller screens than other Palm devices. 2000 was also the year that Palm officially separated from 3Com and went public. If you decided to invest in Palm on Nov. 3 of that year, you would have paid more than $450 a share. Today, Palm shares are trading at just less than $6. Whoops!
