What do you mean? Nintendo first came out with GB classic, then GBC which added color, then GBA which added more power, then added DS with more power and touch input. DSLite, GBA SP and GBmicro are the same as PSTwo and PSOne. They do add small things like better screens, smaller form factor, etc. PSSOne and PSTwo is no different and I don't see PSThree being different either. SONY may even do the same thing with PSP, but it'll be kinda difficult to make it smaller with the UMD drive and all. Yes you will have to eat up your words.
Original Gameboy "brick."
Play it Loud series, better battery life, slightly smaller, better screen, colored exterior.
Gameboy Pocket, smaller, better battery life, better screen (I believe actual black and white instead of shades of green).
Albeit, the previous 3 came out very far apart, long enough to warrant actual hardware upgrades.
Gameboy light, Japan only, a gameboy pocket with a gameboy light, despite nintendo claiming a backlight was not needed and infeasible.
Gameboy Color came out around the same time, I thought it was well done except for the way underpowered hardware.
Gameboy Advance started got the hardware to a decent power, but had horrible ergonomics and somehow the screen was much harder to see.
Gameboy Advance SP.
Then Gameboy Micro and Nintendo DS and Nintendo DS mini. There was also a Gameboy Advance SP with a brighter backlight (or an actual backlight, the original was frontlit) but that's not such a big deal, it was advertised but nintendo has updated the screen before without mentioning it.
BTW, any other colors on the Nintendo DS Mini? I think the system looks like crap compared to the original DS, at least in white, looks too toylike.
