HP TouchPad

WebOS showed up beautifully on its first tablet even if it wasn't fully utilized. The TouchPad also delivered Adobe Flash-enabled Web browsing, Beats audio enhancement, and impressive compatibility with third-party calendar, messaging, and e-mail services. On the downside, it had a thick profile, a smudgy display, and it lacked a rear camera or HD video capture. What's more, it wasn't enough to really compete with the iPad 2 or the hottest Android devices.

CNET review bottom line: The TouchPad would have made a great competitor for the original iPad, but its design, features, and speed put it behind today's crop of tablet heavyweights.
