Fatal flaw(s): Underpowered, poor software, ahead of its time

Before the rise of the netbook, there was the Foleo. Meant to be an easier way for Palm users to write and receive e-mails, edit their calendars, and type memos and notes, the low-powered notebook suffered from harsh criticism from journalists and analysts who said there was no market for a product that was not quite able to fit in pocket, but not full-functioned. Before the Foleo hit stores, Palm CEO Ed Colligan announced that the company would be cancelling the project to focus on its core products.
