If it is me as an adult, I'd just leave it at home. Check.
If it is me as a kid, I can leave it at home and bring it to my friends or school (quietly!). Check.
If there's an electricity blackout, I can still play without having a UPS or an expensive, loud, automatic genset. Check.
Well, I guess it's great.
The spec seems to be between PS3 and PS4 or Xbox 360 and Xbox One.
IMO, if I have to look it in mobile gaming perspective, since I see this as a handheld, I never expect for a better / faster spec, but more on how I can enjoy the games with it or not, regardless of the graphics. It's like when I decide to buy PS Vita, Nintendo DS, and/or an iPad Pro, but not when I decide to buy PS3 or Xbox 360 and/or a PC.
However I'm more worried on its iteration. Again if I look at mobile gaming perspective, then it also compete directly with those mobile phones, if not PS Vita and others. Meanwhile, mobile phones iterate so freaking fast like PC components, leaving this Switch away from the spotlight over the intensive marketing of those phones, regardless of the spec. Yet, I can only see the iteration of this Switch to follow the same pattern of those gaming console does; which takes lots of years to release its next version.
