The Sidekick's swivel screen is gone, it's no longer running the famed Danger OS, and it's now made by Samsung instead of Sharp. Despite those changes, the newest version of the T-Mobile Sidekick is high on our list of new products. Why? Honestly, partially because of nostalgia. But more so because it's a very well-rounded device that makes communicating with friends via social networks like Facebook and Twitter, or through SMS, easy as hell. The keyboard is back to its legendary status and it's now got a touchscreen. The 4G isn't really 4G, true, and the screen is a bit washed out, yeah, but--but! The experience is greater than those few faults. Sidekick back!
