So I started off this morning talking with N5omniac about him upgrading his Nintendo 3DS for the upcoming Metroid release and it got me thinking about the history of console revisions over the years. 

Consoles have had revisions over their lifetimes almost since the beginning. These have ranged from minor cosmetic changes all the way to the more recent completely new hardware of the PLayStation 4 Pro, Xbox One X, and New 3DS systems.  

But what really got me wondering is what people thought of these changes. What were their favorites....and their most hated. Where had a manufacturer saved a system to someone with an improvement or completely botched it up to another. 

So I asked a few people from the site and sent it out onto Facebook and Twitter to see what people thought. What were their favorite revisions, and their most hated.
