I lucked out, I got my switch in pretty early today via Amazon (10:30am, which is rare for me), hell I got it before I had a chance and pick up my BoTW and Pro Controller pre-order! Here is my early impressions of the Switch:
-Setup was very easy. Took about 5 minutes to get to the home screen (Reminded me a lot of setting up a iOS/Android phone), and then took less then a minute to install the day 1 patch for the switch and about a minute for the BoTW day 1 patch. Hardest thing I had a issue with was the Nintendo Account for the eShop, but that was because I forgot to register for the new account system and was trying to use my unmodified Nintendo ID stuff from the Wii U.
-Titles are pretty quick to load, and Zelda does not take too long to load up.
-Physical setup was also very easy, and pairing controllers to the Switch is easier then the Wii or Wii U, which I always felt was a pain. One minor complaint is the USB-C adapter for the dock feels a bit shorter then I would have liked.
-The joycons feel pretty good in the hand and when they are in the shell they do not feel as bad as I was expecting. A bit cramped, but nowhere near as bad as some of Nintendo's other controllers. They also feel a lot more sturdy in the Switch then I was expecting (although you still want to be careful, there is a release button on the back of it). The pro controller reminds me a lot of the Xbox One controller, and the Pro controller does come with a USB-C cable for recharging.
-Swapping between the dock and portable mode is pretty flawless. When you switch to a pro controller or the joycons after docking/undocking, it asks you to hit the shoulder buttons to sync it and then press A to continue. Pretty simple. I have personally not had any issues with syncing yet.
-The switch itself gets rather hot when taking it out of the dock, to the point where I would worry giving this to a younger child. I also worry that this might cause some defects.
-The fan is also rather loud, a LOT louder then when I had my Nvidia Shield Portable. It does seem to change fan speed depending on temperature though.
-I worry about scratching the screen every time I put it in the dock or take it out. I kind of wish it was designed a bit differently or have a open design in the front or some padding on the inside.
-Everything is much more bare-bones then I would like. I really wish there was some app support or better options on the eShop, or just some functionality that other systems do. It just seems like a waste to have this tablet option and do nothing with it at launch, not even Netflix.
-All saves are currently store on the switch itself and cannot be transferred to a SD card nor another switch or backed up anywhere. That is pretty bad and needs to be fixed.
-It is pretty heavy in portable mode, and is something you will want to get a case to store it in. It isn't nearly as bulky as the Wii U controller though, which is good.
-Battery is pretty bad as previously reported. I went from 100% to 70% in no time in Zelda. When not in a game, it isn't too bad, but still.
-This might be because I am playing on a fairly high quality TV (55 inch 4K 2015 Sony Bravia), but the screen quality on the tablet is not as colorful as I would like. It is not terrible and defiantly a step up from the 3DS, but it looks a lot more washed out then I would like. With that being said, the TV mode looks great and even with Zelda being in 900p, it still looks quite good. Honestly, I am just impressed on being able to take recent console quality games on-the-go with me. I am worried about some of the titles that will run in 720p though.
-I wish the right joycon had some of its buttons moved down a bit. Its not bad, but does feel a bit weird. I also wish the + and - buttons were not so close to to the picture and home buttons on the Pro controller.
First impressions are good for the most part and I am liking the switch, but I am worried about the actual power of it and how viable it will be with bigger titles or 3rd parties.
