Allot of Original Xbox consoles had a technical flaw where the clock capacitor would leak causing (often) irreparable damage to the systems.

Don't put words in my mouth, never said I hate the Xbox One, I actually like the console and I do own one.

The Xbox One is redundant because it's game library isn't exclusive, everything can be found elsewhere... Be it PC, Switch, Playstation, Xbox, Xbox 360 and eventually every Xbox One game will run on the Xbox Series X.

Exclusive means to only be found on one device, not several.

If this is a dig because you think I am a Playstation fan... Sorry to disappoint, I'm not, I don't care about any console brand. - Either way, this isn't an argument about Playstation consoles, this is an argument about Xbox consoles.

Doesn't matter what platform the Sports games are on, they all eventually end up in the $2 bargain bin, the platform they release on does not change my disinterest in them.

The N64 controller never prevented me from getting immense enjoyment out of amazing games like those I mentioned.

And just for the record, the Xbox 360 is my #3 top system ever.

Me mentioning the PS 1 and PS 2 wasn't a dig at Sony those two are the best known backwards compatible consoles I could have easily mentioned other consoles and devices like the Wii U, Nintendo DS, Atari 5200 and Sega Power Base Converter.  I owned all previous Sony home consoles and currently own a PS2 slim, PS 3 super slim and PS 4 slim.  Unless the series X gets a radical redesign of its entire architecture once it gets a slim model, the X Box S will always be the cheapest in both console cost and power consumption cost and easiest way to play all X Box and current backwards compatible games so it will never become redundant.  Also I say it again the X Box has exclusive games just because they don't appeal to doesn't mean they don't exist.

Backwards compatibility may be a selling point for you... And it's most certainly a positive selling point for me, but it's not for everyone.
I already own a substantial OG Xbox and Xbox 360 game library with consoles to match, it's not a must-have feature, it's nice, don't get me wrong, the enhanced titles really made the scheme worth it, but sadly were few and far between.

Either way, the Xbox One is not compatible with every single Xbox 360 and Original Xbox library, the Xbox One is only backwards compatible with 27.6% of the Xbox 360 game library and 4.09% of the Original Xbox game library.

But the Xbox Series X will be compatible with every Xbox One game, even the games it's backwards compatible with (I.E. Xbox 360 and OG Xbox) thus from a games library perspective, the Xbox One is a redundant console, there is still a point to keep your Original Xbox and XBox 360 consoles as there are still games on those devices that cannot be played anywhere else. (I.E. Naruto: Rise of a Ninja)

Now it's interesting you bring up something like the WiiU... The WiiU is backwards compatible with the Wii, but in doing so... The Wii still remains relevant as the WiiU is not backwards compatible with the Gamecube like the Wii.

Something like the PS2 having full hardware support for PS1 games, did certainly make the PS1 a redundant console, better off buying a PS2 instead.

The Gameboy advance having hardware backwards compatibility with Gameboy/Gameboy Colour games certainly made those prior devices redundant.

Feel free to name them.

You have Halo 5 which is the only notable exclusive... And that title was fairly average for a Halo game... Also released a long time ago.
There is Forza 5, but it's a Forza game, you only get one every year.

Rare Replay is a collection of games from other devices, so whilst technically an exclusive release, the games themselves are not.

Gears of War 4, Gears of War 5, Sea of Thieves, Killer Instinct, Ori and the Will of the Wisps/Blind Forest, Sunset Overdrive, Halo: Master Chief Collection, Halo Wars 2, Sea of Thieves, Recore, Quantum Break and more are all... You know. On PC or other devices, thus they aren't exclusive, they are all solid games though.

Even though the X1 S and X1 X are ancient technology at this point you can't buy a brand new pre build PC that includes a X1 controller with a 1TB HDD and UHD blu ray drive that can actually play all those games at least halfway decent at the the same price point so that is pretty much like comparing apples to oranges.  Plus I'm pretty sure that achievements on the PC aren't as well integrated as they are on the X1 or even the 360 so its not exactly the same experience.  The few 1st party MS games that are available on Switch don't look or play as good they don't have achievements and you can't play them with a X1 controller so again a totally different experience and another apples to oranges comparison.  Plus you completely ignored my vaild point that X1 S will more then likely alway be the cheapest and easiest way to play all X1 games and current library of backwards compatible games.  So nope the X1 isn't redundant an more then likely never will be.

Also l hate to burst your bubble but Forza Motorsports and Forza Horizon are two completely different games.  Forza Motorsport 8 will more then likely not show up until early 2021 and Forza Horizon 4 came out in 2018 so yeah they don't come out every year.

Never said anything to the contrary, making this post redundant.

Now you are delving into a logical fallacy and shifting the goal post, the discussion was never about cost.

Secondly... Anyone who buys a PC with a 1TB HDD and UHD Blu-ray drive is essentially pissing money into the wind, that's old technology, the PC is entirely digital, HDD's and Blu-Ray drives are obsolete... If you understood PC gaming you would have known this.

A Ryzen 4700u notebook will run every single base Xbox One game just fine at equivalent settings, that's integrated graphics...

But hey, I can use that same argument against you... The Xbox Series X will be more expensive than the Xbox One S All-Digital edition console, does that make it a crappier device? No. No it does not. They both have their place.

Obviously you aren't "pretty sure".
Steam has a fantastic achievement system and implemented it back in 2007. It's far from new.

So you can predict how the 9th gen is going to play out and what the cost of hardware will be in 10 years time? Very much doubt it.

A Ryzen 4700u notebook is way more expensive then any X1 console heck it will be way more expensive then a series X. PC's and PC components have a way shorter shelf life then home consoles they will always be way more expensive then consoles.
