I have seen these questions a lot lately. Which one is better, the Sidekick Slide or the Sidekick LX? What differences are there between the Sidekick Slide and Sidekick LX?

Boygeniusreport.com has a great article comparing the two.

Here are some excerpts:

Screen

Sidekick Slide: The Sidekick Slide’s screen has a resolution of 320×240, and is exactly the same physical size as the Sidekick iD. Even though it is quite smaller than the LX, the Slide’s screen is crisp, bright, and shows vivid colors.

Sidekick LX: We’re in love with the Sidekick LX’s screen! At a resolution of a 400×280, it provides ample room when web browsing, or just doing general tasks with the device. This is the main reason we’re so inclined to stick with the LX. It really is fantastic.

Call Quality

Sidekick Slide: Motorola integrated the ear speaker on the actual screen panel, instead of the d-pad where all of the ear speakers have always been housed. This was an awesome move, and provides the most clear and not awkward talking experience of any Sidekick to date. It is also incredibly comfortable.

Sidekick LX: As we mentioned above, the ear speaker is housed on the d-pad which is on the left side of the phone. We don’t normally use the Sidekick devices as phones, but when we tried it out, we noticed a buzz / hiss through out all conversations, and after a couple minutes the d-pad started to get annoying.

Conclusion:

We hope you liked our head-to-head battle between the Sidekick Slide and the Sidekick LX. What’s our ultimate conclusion? If you’re a hardcore Sidekick user you’ll want to grab the LX. The keyboard and screen alone make this a win. The Sidekick Slide isn’t really beneath the LX on the totem pole, so if you want an awesome phone, but love the Danger OS all in a small device, you will definitely want to pickup the Slide. It’s a hard choice, believe us. We switched from the LX to the Slide, back to the LX probably 6 times alone in the past day, but for now, we’re sticking with the Sidekick LX. The screen is just too good…
