That's just my theory though, I may have to ask the game store clerk for more details. You can trust those game clerks since all they do is import and sell games, have no official affiliation with Nintendo.
I go with Gray Joy Cons because the Neon ones sold out in the store that still has Switch on shelf. I remember I saw it a day before I went and bought it, next say it was gone (Obviously someone had bought it before me). The clerk told me that the Gray is actually more popular in Taiwan since it won't get dirty easily compare to the neon colors. They also told me I can buy a pair of neon Joy Cons with the console, but I can't due that budget wise. You have to keep in mind though Joy Cons are pretty expensive.
And look, the bottom of the Joy Con do get scratched after a few times of taking in and out of the Switch. Again, not that big of a deal. I also said that straps are actually pretty easy to put on and take off if you pay attention to the + and - marks and the lock. Hope this doesn't offend anymore, but those who complain straps
isn't easy to use and easily gets stuck are just dorks. I do hope the make the + - marks more visible, they made the lock white which is good.
Compare to Wii U, the Switch itself, Joy Cons, Pro controller are all better. Switch has quiet, simple and snappy UI. Unlike Wii U which was more complicated, and it took a long time to load eshop and games. The controllers on the Wii U took more time in order to sync, you will have more chance of doing sync by yourself too. The Joy Cons though, simply press the button they will sync instantly.
By the way, does the home button on the right Joy Con glow? Just curious.
So as for now, I have no problems or complain with the Switch, yet. I do find the charger being a bit bulky though. The last thing to test is the game cartridge slot, I hope to get a game to play soon. Mario Kart 8 Deluxe, Splatoon 2, and Breath of the Wild are definitely on my list. Future must-have for me is obviously Xenoblade Chronicles 2.
