The Vita was a great handheld, my only two complaints about it is they went with a expansive Sony memory format instead of SD card, and they did not include the ability to output to TV like the PSP Go had. Incidentally I was not surprised at the success Nintendo had when they released their own take on the Vita with those two issues fixed.

Nintendo happened to release one of the best games of all time at the launch of the switch. That had a huge amount to do with it.

It did without a doubt, but that same game was also available for the Wii U, which was easier to find and costed significantly less than the Switch. Having a killer app helped generate interest, but people actually liking the gimmick is ultimately why the Switch succeeded.
