I agree as long as it concerns my own needs.
Consoles are good for gaming of course, but it's a very limited gaming, and good especially for, but not exclusively, a younger audience. When I was 12 years-old or so, if you told me anything about a "PC" all I could think about was the monitor itself, and a orange & black screen with lots of text on it, it was far from being at the center of my interests for games, and back then it was extremely expensive. At that age, before that, and a little after too, Consoles were best suited for gaming.
But then as I grown older I started to hear about the Internet, and then to see it, and then to experience it, and then to wish I had it. Inevitably I had to get a PC for Internet, and then later on get a "good" PC for gaming, which is exactly where I started to realize the potential behind PC gaming, and how restricted Console games were.
As a matter of fact, the last Consoles generation (XBOX, GameCube, PS2) started to imitate PC gaming by giving extra content from a broadband connection, similar to patches, or new maps, new weapons, new this and that. If we go back in time with the SNES and Genesis it was a game released and that's it, no corrections were possible after its launch, so if there was obvious and game-play influencing bugs you were stuck with them for eternity. But with the last generation and of course even more so with the current generation Console gaming is doing almost exactly what PC gaming has done all those years, which is to increase a game's longevity by making patche(s) for it, which sometimes will also include new and official content from the vanilla state.
And perhaps the most important point of them all is modifications to games from the communities. That's something that so far has been almost exclusive, or in fact simply is still to day exclusive to PC gaming. Just name one game, like The Elder Scrolls series, or the Total War series, or the Half-Life series, and infinitively more. All of them eventually saw tons, and I do mean a heck load of mods for them, some of them being almost as good as, if not better than the official content (known as "Total Conversions", one example being Red Orchestra and Counter-Strike, perhaps the two most successful Total Conversions ever known, with the first's team who've managed to make their own company today known as Tripwire Interactive, thanks to a contest organized by the makers of Unreal Tournament). That's something that has never happened on the Consoles, at least not to the same extent and level, and I do sincerely hope that it will never happen on the Consoles because already Consoles have "stolen" Internet and Patches, all we PC gamers still have to cherish are our mods.
That's for gaming alone, and let's not even start with the Mouse/Keyboard combo battle against the Console Controllers. Even SEGA themselves made a Keyboard and Mouse for their Dreamcast back in 1999/2000, because they knew it was the best thing for first-person-shooters and even real-time-strategy games to some extent, however the Dreamcast's case isn't a good example due to the very, very small library of such game genres. A few other Consoles saw a Keyboard/Mouse for them at some point. Again an example of PC gaming imitations, showing how the Consoles almost cry to become just that themselves, PC's.
I myself will always think that PC's are superior in every single ways including for gaming (but so much more). However, I would never buy a gaming-grade PC for my pre-pubescent son and/or daughter if I had one. For them I would definitely seek Nintendo products, for example a GameCube or a Wii, because I know that Nintendo is perhaps the only company that today still stands firm and hasn't forgotten about the children who definitely have no needs for the exaggerated violence given by other game makers. I would be more than proud to buy them a Mario game, or a Sonic game and a few others. But the point here is that Consoles are good, I believe, especially, but again not exclusively, for a young public. That, and also for some nice gaming fun along with the family (that's an extremely rare occasion, but it can yield some classic fun moments given the proper "family oriented game").
