Best and worst console/handheld revisions, and why

[Leynos]

A bunch of stuff I would mention has been mentioned.

So maybe not the best but it was an improvement. Neo Geo CDZ. The Neo Geo CD was notorious for extremely long load times. Sometimes up to 2 minutes! You saw a monkey juggle so there was that. CDZ put a 2X drive in the new model and games loaded much faster. 

I will throw in Wonder Swan Color & Neo Geo Pocket Color. Libraries much smaller tham Game Boy but like GB to GBC it helped games a lot. For a while Wonder Swan Color was the only portal way to play some of the 16 bit FF games.

One of the worst is the last PSP model. Like Wii Mini. They stripped it of anything useful for the time. It was barebones.
