Game Boy Advance SP
In early 2003, Nintendo introduced a new form-factor for the handheld, known as the Game Boy Advance SP (model AGS-001). The redesigned unit resembles a pocket-size laptop computer, including a folding case approximately one-half the size of the original unit. It also sports a rechargeable lithium ion battery, a significantly brighter LCD screen, and an internal front-light that can be toggled on and off. The redesign was intended to address some common complaints about the original Game Boy Advance, which had been criticized for being somewhat uncomfortable to use, especially due to an overly dark screen.
Game Boy Micro
In September 2005, Nintendo released a second redesign of the Game Boy Advance. This model, dubbed the Game Boy Micro, is similar in style to the original Game Boy Advance's horizontal orientation, but is much smaller and sleeker. The Game Boy Micro also allows the user to switch between several colored faceplates to allow customization, a feature which Nintendo advertised heavily around the Game Boy Micro's launch. Nintendo also hoped that this "fashion" feature would help target audiences outside of typical video game players, much like its Wii. The Game Boy Micro lacks the backwards compatibly with Game Boy and Game Boy Color games.
