-The handheld screen is nice, and hits the right size between too large to carry around and too small to properly enjoy console-style games.
-Joy-con are cool, and not as uncomfortable as I feared due to their size. Switching them in and out of the different configurations is a bit harder than it should ideally be due to the placement of the release button, but isn't as big a deal as sites are making it out to be.
-The controller holder included with the system should have a charging port IMO and apparently the ones you can buy separately do. Nintendo is brutal with the accessories for this thing in terms of price and what's included.
-It transitions from TV to portable really fast with nearly no interruption. You don't have to suspend anything or wait for it to load up. Unlike the Wii U menus, it appears Nintendo went with a snappy processor for the Switch.
-The kickstand is really flimsy and I'm afraid it will break every time I use it. This is a shame because propping it up on my desk and detaching the joy-con is a configuration I enjoy. Just be careful with it when you start.
-The cartridges load fast, which is an obvious advantage of using a cartridge vs a disc but one many people online seem to not be aware of.
-Related to the above, you don't have to install part or all of the game like on Xbox or PS4 if you buy the game physically. This makes the 32gb storage of the Switch easier to accept.
-Fuck the Pro Controller's price, man.
-You should already expect this going into a Nintendo system launch, but there are practically no games and no Virtual Console at launch. Luckily there is a Zelda game available that is shaping up to be one of the best the franchise has seen.
