The Sidekick LX is the latest member of the Sidekick family, and brings quite a feature set. Multimedia is covered by a 1.3 megapixel camera with flash, a built-in music player application, and a microSD card slot for expanded memory. Upgrades from its predecessor, the Sidekick 3, include an improved screen, quad-band GSM (850/900/1800/1900MHz) support, and a 3.5mm audio jack. The question is, does the Sidekick LX live up to the Sidekick family’s reputation for being IM/Email powerhouse devices?
Physical Aspects The Sidekick LX weighs in at a hefty 162g (5.7oz) and measures 130mm x 60mm x 17.9 mm (5" x 2.4" x 0.7"). It’s no secret that this thing is big and heavy, however Sharp has reduced the size over previous models, especially with regards to the Sidekick’s thickness. The build quality is solid, however, with no creaks. The main display swivels up with a very satisfying snap, though there is quite a bit of play throughout the opening motion.
