It was a pretty good budget offer – often with Mario Kart Wii included. Brand new and just a hundred bucks. Pretty clear they had to cut some corners (complex mechanics of the slot-in drive had to go as well) to deliver a somewhat usable console that can be called a Wii.
Cutting away those few smd mounted things (capacitors/resistors/whatever) for supporting higher quality picture output for saving a cent on each unit was going a step too far in my opinion. Everything else: Cut away what is possible and keep that retail price down!
As for the save management:
- The Wii U doesn't allow this at all (for Wii U software) as far as I know – not taking homebrew software in account.
- The 3DS doesn't offer decrypted backups usable on other consoles and doesn't allow backing up Pokemon saves.
- Switch… I don't have one and hardly read about it. Isn't this topic (backing up saves) part of a paid cloud service?
I’m talking specifically about the ‘normal’ Wii because it offers this option.
I remember at the time my mum got a decent enough second hand Wii with GC BC, Wiimote, WM+ dongle and Wii Sports/Resort for £60, so I don’t consider it a good deal unless it had to be new. Plus if you later decided you wanted homebrew, etc. you were stuck with the Mini until relatively recently.
I also think they could have created a way to allow for at least a one way transfer to a Wii U via USB (so no save hacks on the Mini itself). At least in the case of component, etc. there was a physical cost associated to it and composite was likely the most common connection used, even if it just made Nintendo look cheap.
In the case of the other consoles though:
Wii U does offer save backups to USB and there is a Wii U to Wii U transfer utility
3DS did also offer a way to backup/transfer saves and AFAIK most carts saved to the cart
Switch does require online subscription for backup (something I also dislike, at best it’s ‘better than nothing I suppose’).
