I actually don't lack incentive, my reasons for anything like this is usually "why not?". I was going by what we have seen in multiple instances of homebrew communities/scenes prior to now, and not just the xbox, wii, PSP, GBA and DS.
You fear I might be unintentionally introducing a catch 22 type arrangement (no devs so no devs come in, and possibly even hindering build it and they will come)? The comment was more addressing the "people still hack them today" and yeah they do -- pick one up for nothing at a car boot sale and you can do very nicely, and probably easier than setting up a raspberry pi or if you are plundering an old game library then it is a really nice perk. If you are looking at setting such a thing up then barring one of those wii u fire sales the wii u is not an attractive proposition for it, possibly even if it did have a solid homebrew base.
On potential.
The 3ds is a sub GHz older ARM device with comparatively weak 3d, low memory, passable storage if you count the SDHC cards, bad IO (no usb, no bluetooth, no external breakouts...), sub par networking, not very nice screens and likely always a crappy development environment if you consider Nintendo does not care for it.
It has buttons by default though I guess.
edit. Missed a reply. "this is a forum those which like"
No, not at all. It is a forum to discuss it. If you are going to be disruptive or categorically opposed because hacking is bad then yeah you will probably be shown the door. You don't have to be endlessly positive though.
I think you and I are reaching a point of agreement. Although I personally disagree with your last sentence. But that's just my opinion.
The Wii U and even the 3DS have something that almost every other console does not have, dual screens. This opens up the possibility of some interesting uses for those dual screens, and I've heard several ideas on how to take advantage of the dual screens. Also, the Wii U is more capable than most people give it credit for.
I would absolutely love it if you, Quark or CreeperMario would teach me some programming techniques for the Wii U at some point. I have been looking at it for the last week or so, but my AC has been out and it's like 95 degrees at my place. I've been staying at my gf's and I obviously don't have my Wii U here to start programming on. Message me or hit me up on Skype (I'm CJB100 on there too) if having a student sounds interesting lol. Otherwise I will just message you guys when I run into snags.
