I've gone with Nintendo+PC for several generations now and the case for the PC as a game platform is stronger than ever. Beyond the PC's traditional strengths (better support for genres like RTS and grand strategy designed around a keyboard and mouse, free online connectivity, modding, no dependence on shared home television sets, existing ownership of a computer for other purposesand note how the last point is the biggest attraction of mobile these days) the biggest factor, bar none, is price, price, price. All you need is the patience to wait a year or two for the major multiplats to drop to a fraction of their release-date MSRP, freeing up the budget for games that retain their value like those from Nintendo and Blizzard, which have traditionally overlapped with my day-one priorities anyway. Staying behind the curve also makes it unnecessary to invest in building the most powerful rig available, and if you do choose to build one, you can safely do it with years of forward compatibility in mind. I caught up on nearly everything that interested me about the PS3/360 libraries on my day-to-day notebook (and in higher quality, too), which was already a sunk cost regardless of what I could or couldn't play on it. And since a lot of those titles were never first-rank priorities for me anyway, the difference was between playing them cheaply on a PC or not playing them at all.
Essentially, software has become so radically more accessible on the PC compared to what the platform used to boast, both in price and library diversity, that a PC-based player can exercise the same habits as he or she would have done a decade ago but now with access to a considerably larger selection of games, and on the same budget as before. I can see the attraction of a PS4 for someone who primarily plays on a home theatre setup and wants guaranteed compatibility out of the box for the next five to seven years without fiddling with settings, but for my use cases those advantages are not by themselves persuasive. Unless console exclusives are your top priority for software (which is the case for me with Nintendo), or you cover all your home computing needs with a cheap netbook or tablet, there is little reason not to use a PC as a total console replacement. It's not as prohibitive as people think, and there isn't even a need for a custom rig if one is intimidated by the process of ordering parts and assembling a computer (not as hard as it seems once you make the jump and do it, but an understandable obstacle for many), especially if you don't care to acquire every big title on day one and run it at the maximum settings.
