20. Gizmondo (2005)
OK, itâs here more for the amazing backstory than the qualities of the handheld itself, but Gizmondo did momentarily look like a contender back in 2004, offering text messaging, web browsing and video playback as well as mobile gaming. But then the founders burned through millions of investor funds on Regent Street stores and extravagant launch parties, and the whole thing collapsed in spectacular fashion, symbolised by one execâs (non-fatal) 200mph Ferrari crash on the Pacific Coast Highway.
19. Sega Dreamcast VMU (1998)
Admittedly, there was not a huge amount of developer support for Dreamcastâs amazingly idiosyncratic memory card/handheld console hybrid, but the fact that it even exists warrants it a place on the list. Despite its teeny 48 Ã 32 dot LCD screen, the VMU did support a range of mini games including a Chao pet sim in Sonic Adventure and Zombie Revengeâs surreal Zombie Fishing.
