They didn't include the Tiger Electronics R-Zone? I am amazed. Though not at its exclusion so much as at the fact that Tiger actually thought the R-Zone would qualify as anything resembling a worthwhile gaming device.
To answer a few stray questions about consoles, the Mega Duck was a derivative of the Watara Supervision, and was meant to be a "Game Boy killer" (much like the Watara Supervision itself was supposed to be). It was released in 1993 and did horribly. The Master System 2 was a redesign of the original Master System, which was technically the SG-1000 Mark III. SMS2 looked a lot more like the Genesis. Bally Astrocade was a short-lived console from 1983 that didn't get a lot of attention, and was one of the first "PC/console hybrid" systems.
Sega Nomad was actually a fairly well-known one, a handheld variant of the Genesis. Like its predecessor the Game Gear, it had horrible battery life and a very blurry screen. The LaserActive was and (accounting for inflation) still is the most expensive video game console ever released, and also the only system in history to include add-ons to play games from other systems which cost more than the actual systems that were being emulated. XaviXPort is basically just a cheap knock-off from 2004 that nobody remembers, and had only one noteworthy feature: wireless controllers. Tapwave Zodiac was another would-be "Game Boy killer" from 2001 that actually got a lot of revisions and eventually got mixed up to become a "DS killer". As you can imagine, it failed horribly.
Sky Render - Sanity is for the weak.
