Sorry, I think they mostly kind of failed at this. I think PS1 and PS One looked good, after that they were mostly pretty ugly. I didn't like any of the PS2 or PS3 designs. I think the PS4 slim looks okay, but only that. Their handhelds look pretty nice though, especially the Vita.

I remember Nintendo used to be the ones that people laughed at, when it came to design, they have improved a lot, and have been consistently good since DS Lite, except 2DS perhaps.

Microsoft is hit and miss. One S might be the best looking console period. The Original Xbox and the The Original Xbox One were pretty ugly though.

1. Original PS1
2. Slim PS1
3. Original PS4

I don't know what to think anymore.

I own the original and a Pro. 

Based only on the original designs:
4 > 2 > 1 > 3

The 3G PS Vita is my favorite PlayStation and device. It is nearly a perfect design. Just needs to shift the sholder buttons forward, add L2/R2 behind them, and make the sticks clickable. That would be an absolutely perfect device.

Home console wise, I can't decide between PS2, PS3, and PS4 Pro.

Fat PS3 if it was smaller looked badass.

But Original PS4 design was fantastic. Size of a PS3 slim with insanely better components, good heating and the power supply inside the console. Ticked every box.

My favorite is definitely the launch PS4. It was so sleek and smooth

The fat PS3 was just ridiculous imho. That cheap lettering and tacky and huuuge design never appealed to me. The Slim was so much better.
Extra Slim PS3 though was my least favourite Sony console ever.

I'd say the original PS4. It's just a nice, sleek design. That line with the blue light is a nice touch.

I disagree the Xbox One S is full with holes like cheese on the top, everything gets inside the Console
