I love my Wii U, for different reasons.
First, i was able to play Wii games i missed.
Second, The web browser is the best. Every day when i go to bed i start up my Wii U and use the browser. Its fast and its easy to type with because of the touchpad+stylus. As far as web navigation goes, its just alot more usable that any other system.
Third, just like with the gamecube, theres alot of gems that only come out on Nintendo systems. I love the selection of exclusive software. I was never a huge fan of multi-plat games because i feel they dilute the focus necessary to make a better product that focus on the hardware its beeing created for. I think games like Bayonetta 2 and Mario Kart 8 are proof of how you can achieve so much more on the graphical level if you only focus on one platform.
Yes, it is basically my secondary system, but at the moment its the most used (even though it isnt for gaming purposes), but its exclusive offer makes it well worthwhile and i'm satified. Would i like for there to me more games? Well, sure, who wouldnt (its not like the competition is doing better on the exclusive department)? Do i miss multi-plats? Nope, its not the reason why i bought a Wii U in the first place.
