The Game Boy Micro, released in 2005, managed to squeeze in the standard headphone jack despite a massive decrease in size from the GBA SP (a squint-inducing tiny screen helped on this score).

Early pre-order sellouts for the iPhone 7 Plus model suggest a lot of smartphone buyers don't think the missing headphone standard is a dealbreaker either.Still, following the GBA SP, Nintendo didn't develop a long-standing aversion to the standard headphone jack. The revamped system sold 43.52 million units worldwide, according to Nintendo, representing over half of all Game Boy Advance units ever made. In any case, the lack of a headphone jack doesn't seem to have hurt the GBA SP much in terms of market impact (though the lack of any serious competition before 2005's PlayStation Portable may have something to do with that, too). If you wanted to charge and listen to headphones at the same time, you had to invest in an awkward third-party solution, which should sound familiar to iPhone 7 watchers. To use headphones with the GBA SP, you had to buy a $5 dongle-not included with the $100 system-to plug into the EXT2 port, which was also used for charging the system (there were also custom-made headphones that plugged into the EXT2 slot directly). It also sported a trendy flip-top design that protected the screen when not in use and made the unit easy to fit in a pocket.But much like the iPhone 7, the GBA SP did away with the headphone jack that had been standard in the hardware line up until that point. Still, the GBA SP drew interest as the first Game Boy to sport an internal battery pack (boasting 10 to 18 hours of continuous play) and the first to include a frontlit screen, for playing in dark rooms. It didn't support any games that weren't also supported by 2001's standard Game Boy Advance.

Nintendo's mid-generation revamp of the original Game Boy Advance didn't improve on the internal processing power of the core system.
