What is this strange notion we have these days...
First you build a console and sell it. Then you start removing functionality, and sell it for what the original console is now reduced to.
*PS3 has lost functionality with every redesign.
*DS Lite lost the GBA port when they made the DSi.
*Wii loses GB functionality when it goes slim.
*PSP Go lost the UMD drive (and suffered for it).
Back when I was a kid, the rule was release a console, then release more add-ons that enhanced its functionality, not rip bits out.
*The Super Nintendo had an adaptor *added* for Game Boy games. It also got one for satellite service in Japan, and god only knows how many peripherals. Still got my Super Scope, region adaptor, etc.
*The Mega Drive had two major hardware upgrades, and several integrated redesigns that were more advanced than the original. The games might have been shit, but the attempt was there.
*The N64 was given a hard drive.
*The PS One supported an external monitor (though they did drop some ports due to the smaller size)
*The PS2 slim came with the network adaptor integrated, rather than being a separate add on (though again lost the expansion bay). And what about the PSX?
Surely this is the selling point of a redesign or upgrade? More kit!
