Nice.
Absolutely love mine and play it on the go probably more than I play it on the TV lately, like (lunch breaks at work, traveling a lot, etc.)
Battery life is better than I thought and I don't know how they squeeze out 5 hours playing something like BotW on such a large high-def screen.
Heat hasn't been a problem for myself either I've tested it multiple times and it never gets too hot in the middle of BotW action.
Only games worth getting at this point are BotW and MK8. Splatoon out Friday and we are getting it from Prime in the afternoon, both myself and daughter psyched I think it's our weekend.
There's going to probably be endless good games on this, just from what we know, Splatoon 2 (all reviews say it's awesome), Mario Odyssey (looks like it'll be the best Mario game yet), Yoshi, Kirby, Metroid 4 (probably the best Metroid that will come out thus far), Xenoblade, etc etc.
The console has done so well, third parties will for sure jump in on this.
