Why did you buy a Wii U in the first place?
I tend to look on the bright side of things, and I won't fault you for what you did. PS3 has a plethora of good games and you can enjoy those - plenty of them are cheap too. And since you have + you will have access to the instant game collection. You can always get a Wii U later when there's actually a library worth buying the console over. I intend to get one as well, but no way in heck will I buy one now. I probably will wait for a hardware redesign since I have grievances with the current SKU (tablet battery life, lack of Ethernet port, piss poor memory, etc, etc).
