Uhh yeah.

Sony PlayStation Portable (PSP): Launched in 2004, the PSP was a significant competitor to Nintendo's handheld consoles. It had a strong library of games, multimedia capabilities, and a vibrant community. It sold over 80 million units worldwide and was considered a success for Sony.

Sony PlayStation Vita: Released in 2011 as the successor to the PSP, the Vita boasted impressive hardware and a lineup of quality games. While it didn't achieve the same level of success as its predecessor, it still garnered a dedicated fanbase with its niche titles and innovative features.

Sega Game Gear: Introduced in the early '90s, the Game Gear was Sega's answer to Nintendo's Game Boy. It featured a full-color backlit screen (which was a novelty at the time) and had a decent library of games. Although it didn't surpass the Game Boy in sales, it was a popular handheld console during its time.

Atari Lynx: Released in 1989, the Lynx was one of the first handheld consoles with a color LCD display and featured hardware capabilities that were ahead of its time. However, due to various reasons such as high price, limited game library, and marketing challenges, it didn't achieve significant commercial success.

Neo Geo Pocket/Neo Geo Pocket Color: Produced by SNK, these handhelds were known for their excellent build quality and a few standout titles. They had a small but dedicated following, particularly in Japan, before being discontinued due to stiff competition from Nintendo's Game Boy Color.
