OK, kids–hope you’ve been nice this year, because here’s something you might want to add to your holiday wish lists. Today, T-Mobile announced not one, but two new Sidekicks to be added to its lineup: the T-Mobile Sidekick LX and the T-Mobile Sidekick Slide.

Let’s start with the latter since it brings something new to the mobile messaging device: a slide-up screen (all together now: oooohhh, ahhhh). Unlike previous models, which have been manufactured by Sharp/Danger, the Sidekick Slide is made by Motorola and features a smaller design. It measures 4.6 inches wide by 2.6 inches high by 0.6 inch deep and weighs 5.3 ounces, while the T-Mobile Sidekick 3 comes in at 5.1 inches wide by 2.3 inches high by 0.8 inch deep and 6.7 ounces and the Sidekick iD is 5.1 inches by 2.4 inches by 0.8 inch and 6.2 ounces. And hallelujah–it has a higher resolution screen at 320×240 pixels and 65,000 colors.
