I am customizing it all the time. I like to spraypaint my Joy Cons fitting to the current Season.
For Christmas I had them two slightly different shades or red with glitter, last summer I made them full Animal Crossing Joy Cons and right now they are green and yellow! I have also customized a Switch Lite at one point. Feel free to check out all the customizations here
I haven't customised my switch at all though I have considered changing the color of my joycons with spraypaint or something like that (I would love one purple and one hot pink) :>
Not much, but I do have some little cat paw joystick caps! They're red and blue, to match my red and blue joycons. c: I might get a case or a skin for it at some point though.
I haven't skinned it yet but on my lite I put peach thumb grips! I'm so bad at applying any kind of decals/stickers so until I can meet up with friends again mine will be plain, haha! My big switch is already animal crossing themed so I don't think I'd ever put a case on it. Or anything that's not clear at least. I would consider more thumb grips though!
No, because I got the Let's Go Pikachu switch, and it's already so nicely decorated. ^^ That said, I really wanted to get some of those really cute thumb grips, saw a set that was a puppy face and a fox I think, that were in colors that would have looked nice with my Joy cons, but alas, I wasn't able to get them. xc I just have some plain gray ones, sadly.
I haven't customized my Switch at all, and I never will since I'm not somebody who customizes the exterior of their console/handheld/controller/computer/etc
I have a skin on mine, mostly because I had to buy a grey switch lite instead of one of the nicer colours and i just couldn't bear looking at it any more lmao. atm it's got daisies on it but i'm considering buying a different skin! we'll see
No because I have the Let's Go Pikachu and Eevee switch and I don’t want to make it worse by attempting anything that I’ve never done before because it could go badly wrong.
I never customize any of my electronic devices. The closest thing my Switch has to customization is a custom cover for the front of the dock that I purchased off of Etsy years back, soon after I had acquired the Switch itself, because I had seen people saying how they were accidentally scratching their Switch's screens when placing them into the dock even if they were careful because of a design flaw in the dock's construction or something along those lines. Figured it was better to be safe than sorry. The design is just a pattern with skulls, not really purchased for the design itself so much as because it was the best combination of inexpensive price and a design I found tolerable.
