So impressions and reviews are good or bad?
Generally very good. However mixed opinions are thrown in the pile. I'll break it down:
+Great display on the unit
+Fast snappy UI with more features in settings than expected
+Joy-Cons are great with HD Rumble and IR sensor
+Switching between docked and handheld mode is seamless
+Heat output isn't ridiculous during play, and fan acoustics are pretty low unless you're in render intensive areas.
=Joy-Con Grip is OK, you're better off getting the Pro controller for primarily TV use
=Switch kick stand is kinda flimsy but does the job well.
=Launch line up is OK, unless you're really banking on Zelda for the main game. Might wait for more titles to release like Mario Kart Deluxe or Splatoon 2.
-Joy-Con sync issues exist, if you're holding it too far or obscure it from facing the TV the signal will cut briefly. Firmware patch to fix?
-Battery life is pretty short in games, even with reducing brightness. 3 hours in BotW.
-Unit takes as long to charge as it does using the battery while playing 2-3 hours for a full charge.
-Factoring in other accessories to make this console last, the costs for another larger microSD, Pro Controller, and ~10000+mAh powerbank.
