Then I don't understand why you complain about 3 - 10 hours without recharging. Even 3 hours is a lot more than your 0 hours. 

But as we move into digital ecosystems, that becomes the new bar for backwards compatibility as it's one digital copy of a game that works the same as the physical copy of the game. Your PS1 saves can be imported to the newer platforms, which does make it stand out compared to how VC was run. Can only hope that Nintendo keep improving on itself and borrowing bits that work elsewhere.

I think the Vita was a pretty nice piece of hardware, but it's another example that great hardware doesn't necessarily sell consoles. Vita was let down by a pretty poor support of what's important, games.

If you have had psn plus for a few years and always enabled all instant games per month you have probably built up a large library of Vita games, I know I have and have come from the psp too so have many psp games I can play too. Then streaming from the ps4 works well so you can play ps4 games too. It's nicer to hold than the Switch i think. It's great value even now. It doesn't offer the performance of the Switch or have brilliant Nintendo games but does have a large library of very good games and is a better actual portable than Switch being smaller and with better battery runtime. I feel this will be addressed with a later Switch revision though.

Switch already has a better library of games than the PSP during its entire lifetime after only 10 months on the market... just putting that out there... 

I own a smartphone with a far superior camera that already supports video chatting with much more people. I never used the Vieochat on the wii u

What about the gamez?

I thought you were referring to playing outside in itself, which is something I rarely do. I mentioned my 3DS on the previous post to illustrate an example within my own house as to why its 6 hour battery is inconvenient, and I referred to my laptop as the usual time I would use electronics during my student days (not anymore, sucks not doing anything at all, too much free time) which would indeed kill my laptop for good, let alone playing something during boring classes on anything but the lowest brightness setting and without wi-fi on.

For someone like me, who doesn't care for any Nintendo IP aside from Metroid/Xeno, the library sure isn't better than the PSP.

It's missing the key aspect of the Switch that makes it successful, and one of the only ones that matter.
