1) My disk read error Wii says otherwise, and it was quite a widespread issue, as were ejection errors on the Wii, as are sound problems on the GB, and battery problems on old GB games, and rear issues with virtually all NES consoles (even when they werent retro), instability and hardware issues come with taking more advanced hardware, when the 360 and ps3 released they had very new hardware at the time - the wiiu released basically 6 years later with comparatively powered hardware, so its less likely to break, nintendo has almost always gone with much lesser powered than the standard of the time for each release, which benefits the stability.
With that in mind though, there are still people on their first ps3/360 that havent had any issues.
2) Do not get me, or Tamron started on this point, I will simply leave it at this, they "popularized" most of those, they were not the first for most of them.
3) Releasing new colors / special editions / multiple versions of the same hardware in different models / locking out games in the same generation for newer hardware (dsi / n3ds), releasing more REQUIRED addon peripherals for games than all of the other manufacturers combined all say otherwise, you take a dig at xbox not havng recharcable batteries and for charging for play and charge kits yet completely ignore the fact that the wiiu tablet comes with an asthmatic battery and space for the seperately sold larger battery, they could have just included this battery from the beginning.
Then you go off on one about vita memory sticks being proof of nintendo not penny pinching? tell me, if you buy a game for the 3DS that is also available for the WiiU, not even just retail games, but virtual console games too, why do you need to buy that same game again for the WiiU in order to play it, even if both consoles are linked to the same NID?, If i buy a game on PS3 thats available on PS4/Vita/PSP, I can play that game on all of those systems too, without having to buy it again.
4) This is entirely down to the changes in hardware, you cant change an entire architecture and keep backwares compatibility without including the old hardware to run it natively, the GC, Wii and WiiU are all ibm powerpc, so keeping support for older generations isnt hard.
At the same time, we are barely a year in to the XBO/PS4 lifespan, they could both end up adding software emulation support for older games at some point in their lifetime.
5) Selling more software would comprimise there software?
