I'm for the right level of technology for the right price for the time. Last gen, I thought the PS3 was a bit too ambitious and expensive when it was initially released so I bought the X360 before buying the PS3 a few years later. I found the Wii too low specs with gimmick tech that didn't add to the gameplay for the types of games I play so I bought it very late gen and I regretted every buying it in the first place anyway.
This gen I have found PS4 hit the sweet spot right out of the gate and bought it the first year. The XBONE was too expensive at first, but ultimately after the price dropped I bought one about a year ago. The Wii U is just not relevant tech wise. It feels like previous gen tech. I do not plan on buying the Wii U.
