specs are relevant for Home Consoles because of people expecting mind blowing experience with graphics and AI along Huge works to explore. Without good specs developers struggle to get things done quickly and need to spend more time on optimizations instead of pumping out more games. This is where PS4 shines, its easier and powerful to develop for developers so we can get more games done in less time with great details. Wii U lacks power to compete with PS4 and Xbone in 3rd party games but it has some good games but that's not enough for Wii U to survive in todays competition. They are fine in Handheld because of less competition and games doesn't require graphics much.
GAMING is not about spending hours to pass/waste our time just for fun,
its a Feeling/Experience about a VIRTUAL WORLD we can never be in real, and realizing some of our dreams (also creating new ones).
So, Feel Emotions, Experience Adventure/Action, Challenge Game, Solve puzzles and Have fun.
PlayStation is about all-round "New experiences" using new IP's to provide great diversity for everyone.
Xbox is always about Online and Shooting.
Nintendo is always about Fun games and milking IP's.
