Depends entirely upon the nature of the mod in question.

If I can stick a specially named file on the root of the SD that the burned in silicon will load without question then the hard mod had better do something seriously special (overclocking, more processing, dual nand where a virtual one is harder, shared nand, rapid fire buttons, easy access to something I might not have access to, debugging capability and so on) for me to consider it.

As that is unlikely to happen in the modern world we are back to considering what goes. We might also have to consider the nature of any support for them but I will assume it is acceptable.

Hardware mods. Traditionally a bit harder for device makers to work around which seriously lessens the "my little brother updated" type thing. If they come with perks like those mentioned above then so much the better.
Software mods. Their only saving grace is being software you can mostly download it for free (there are things that you get to pay for from time to time, sometimes because the people doing the deed are using lots of computing power to make something, other times because the people doing the mod reckon they can get away with it which I guess is fine as well). I don't particularly consider soldering and related activities that troublesome for most of the things out there, would prefer not to have to hook probes onto a BGA though or remove epoxy in some cases.

Really though until we know more about the attack surfaces of the switch and how things will play out it is all basically complete speculation that helps nobody. Such things are a bit of a spectrum anyway -- the average 360 DVD mod could be done on some fairly popular motherboards with a sata lead and then assembled back again, however as it involves pulling something apart it was still hardware according to some, compare that to some of the later RGH stuff where you had to run wires around certain locations to avoid inducted noise... it is not even close.

 

Software mod is better, cleaner, cheaper, and you don't void you warranty either (well, if you can remove the patches and/or update to a newer official firmware, and if the damn thing still works, at least partially, to be able to do these).

But if you send it into warranty with the modchip removed, there WILL be signs of tampering, and there's a very high chance that they will refuse repairs and send it back to you.

 

I am not sure about that. If it is related to the hacking (your mod chip power source overloads something and cooks it and that is all you, your mod probably does not trouble the switches in the buttons, nor the ribbon cable attaching the screen, nor a whole host of other things).
The classic example, and one from several big court cases the world over, is car warranties. https://www.keithmichaels.co.uk/news/vehicle-modifications-and-warranty/
Morally speaking I would have to go with that as well. It could get a bit hazy if we have to consider some aspects of software (some would try to argue any mod there, I would argue it still has to be relevant to the fault) but that is still nowhere near your reasoning.

"outside the warranty period" is a more nebulous concept in Europe where most states have something like the sale of goods act in the UK where things have to last a reasonable lifetime for the device in question -- people saw MS extending the warranty for RRoD and thought it nice, I thought it just something to fall in line with consumer protection laws. The one or two year thing may be the enhanced we send out an engineer/courier type thing but the period itself is a different matter.

 

I have a question that i thing some people should ask themself:

"So you are willing to gave your Switch a Hardware mod and still thinking about the warranty?!"

If you modify your HW (Console/Handheld/Smartphone....) forget about the warranty .... it should be a toy now you can have fun with .... and if something goes wrong during the Hardware mod it shouldn't be a problem for you because thats the risk if you temper with HW that doesn't come from the original publisher.

Only my opinon but i question some answers in threads today because they are very strange IMHO.

 

I prefer software, but that's just because I'm lazy. No problem with hardware mods if that's what it takes.

Warranty, meh, if it goes wrong, it goes wrong. Can't afford to replace it, don't tamper with it.

 

Software. Easy to-do process , most of time its for free and if something goes wrong along the way thats easier to get problems solved. But i honestly dont think thats what we ll be getting.

 

Not clowning, software mods are legal where I live. Nintendo can't get away with a hardware defect whatever software I install on my device. The only thing they can do is repair my device and (probably) wipe the softmod.

It's the same as a phone, tablet or computer. If I break the software it's my fault and I won't be covered by any warranty (although phone companies flash your device for free), other issues MUST be covered by the warranty.

 

I agree it is not a clean cut argument but just as many places also have turned around to specifically allow tinkering with your devices. Consoles do seem somewhat absent (phones, cars, TVs... all other types of embedded computer).
