More reading between the lines here is needed.
Sure, in that post the quote is suggesting that we will be replacing our Xboxes and Playstation's with an iPad, but surely the larger message is that the Vita/iPad/XboxPortable/WiiU (well, Nintendo are nearly there anyway) will not be a 240v powered, stationary living room item.
Rather, I felt they were suggesting that the WiiU and iPad model is closer to what the next generation will be. A powerful system that can be plugged into the 50"+ monitor/TV for hometime gaming, but readily unplugged and taken away with you and not sacrifice the fidelity of the fun (beyond downsizing the screen).
I can't believe there are people against this? Especially given the Vita/iPad/3DS and WiiU are all well on their way to providing this, and people love these different thing already!
