systems to displaying video clips and playing music during those less productive moments of our lives.

Today's newsHere's something that's less a concern to the historians of tomorrow, but front and center for consumers today: Which one to buy. We singled out nine high-end handheld devices (we call them killer PDAs though some fall outside the technical definition of a digital assistant).

Our reviewers put them through the rigors of day-to-day use to help you choose the one that best meets your needs. Among them -- Research In Motion's BlackBerry 8700s, Palm's Treo 700w, and a handful from makers and carriers including Samsung, Deutsche Telekom's T-Mobile, and Cingular Wireless, the joint venture of BellSouth and AT&T .

Some devices in our sample group appeal primarily to the inner workaholic in all of us, while others are more fun -- displaying video and playing music or taking pictures. So those future debaters will not argue the point that for those willing to spend a little money to be well-equipped, there certainly was no shortage of choices.
