I must also say that the WiiU is, by far, my fav hardware from Nintendo in a LONG time. They actually blew my expectations completely out of the water with it actually...
The HD upscale of Wii titles increased the WiiU value exponentially for me as well.
I agree, I had a Wii I never really touched but got the WiiU because I now have two young daughters and it seemed the system to get them started on.
So far I've actually been extremely pleased with it, and the game selection has been more then enough to keep me happy between the ports, first party games and virtual console (though I have less time to play than most). And of course off-tv play, enabling me to play console games while laying in bed (making my Vita work harder for attention).
Also playing Wii games with the clearer HDMI out has been great, including Xenoblade which I picked up on Black Friday and now see what all the fuss is about.
It quickly became one of my favorite JRPGs and imagine my surprise when I found out a sequel was due out in less than a year!
I was a bit iffy when I first got the WiiU, thinking it would just be the family Mario machine, but it's turned out to much better than I expected.
