If you want cheap... You don't want extra mechanical components to drive up price.
Makes absolutely zero difference. Gimmick or not.
And there is a ton of potential cost cutting that can be done to the switch as well.
But why does Nintendo want to go so cheap though?
Removing a desired feature may reduce price but it also reduces value, while removing an undesirable feature lowers cost without decreasing value much if at all, that's the difference. Course the 2DS made the mistake of also getting rid of the clamshell design, so despite being the cheapest model it sold worse than the regular, atleast iirc. Really don't see Nintendo repeating this mistake.
I didn't say they couldn't cut cost, only that they don't need to.
Well if your point is to have much cheaper offer of your platform, than probably you will not have Joy Cons and dock functionality for playing, offcourse you will still have regular Switch, and later probably Switch Pro/XL or even Switch TV. 3DS is dying and they will need low price offer on market when 3DS dies, and this would be basicly Switch Mini/Pocket just for handheld play that would effectively replace 3DS price point on market. Dont forget, Switch is $300 while 3DS covers price point from $80 to $200, we can realistically say that Switch will be at around $250 at end of next year, so they well need $150-200 offer on market also, Switch Mini/Pocket would perfectly fit there and would effectively start replacing 3DS price point on market.
Any reasoning behind the bolded? Why do they need to have a sub $200 system on the market at all times? What makes you so sure that no detachable controllers and no dock means $100 cheaper? Do you believe a smaller form factor Switch would not cost more compared to regular Switch?
