I like the Wii U. I actually hooked it up again for the first time in years. But the hardware is problematic. The processor is slower than the Xbox 360 and PS3. There's only 2 GB of RAM and about 1 GB of that is for the OS.
The GamePad is also required for certain titles or system settings that it shouldn't even be needed for. There's also no ethernet port and only a paltry amount of internal flash storage.
