A shot of the Switch tablet inside
Battery looks to be easily replaceable by the user, though that'll probably void the warranty. And pretty generous amount of thermal paste
edit:
Also if anyone haven't seen yet, reviews are out for the Switch. Now to note, most of the reviews released do not contain testing of the Day One patch, so no access to the online features such as the eShop. But reviewers do get to play games, of course being Zelda BoTW.
Eurogamer's review should come as no surprise, as they tested the technical aspects of the console. Think the most notable bit is the battery life, where Eurogamer did meet the advertised battery life, but not any much more. Of course this is playing Zelda BoTW.
0% Brightness, 50% Volume Three Hours, Five Minutes
50% Brightness, 50% Volume Three Hours, Three Minutes
100% Brightness, 100% Volume Two Hours, Thirty Seven Minutes
100% Brightness, 100% Volume (Powerbank Connected) Six Hours, Fifty Minutes
Full Recharge Three Hours, Five Minutes
To add on, the Usb-C port is at the bottom, so charging while playing may be a bit awkward.
Also the Switch comes with 25.9 Gb of space out-of-the-box, from the 32GB it ships with. Therefore, a Micro SD card is kinda a must if you're planning on a digital library rather than game cards.
And there's been reports of the docked mode not performing as well as hoped. Still some frame drops in Zelda BoTW.
