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?
