I agree it's stupid and pointless to compare specs.
Look at Xbox360 and PS3.
Surely they both have exclusives games, but multiplatform games look and nearly identical.
Comparing the screenshots and measuring how many particles effect or 2x,3x...antialiasing on which hardware looks better is pointless.
The end user, will get pretty much the same game experience on both system
Surely there are other factors that will make it pick a version over another: How strong and stable is the online connectivity, smoother framerate versus choppy, screen tearing scrolling or even loading times.
Since the WiiU will be the newest, smartest kid on the block for a couple of years, I expect faster loading times ( Nintendo always does it ) a decent online experience (better then the Wii anyway ), and a smoother framerate ( since the WiiU will be slightly more powerful I expect multiplatform games to run smoother ).
Let alone the uniqueness of the controller, that could be put to a very good use, and the exclusive first part games that I grew up with and love so much.
I'm sold already.
But comparing specs at this stage of the game, is really childish.
Surely 20 years ago the SNES graphics were a huge improvement ofer the 8-bit consoles of the time, but were pretty close to the Genesis capabilities, and most games could be ported over and played just the same. What's the point in comparing them ?
The games are what matters. Creativity, gameplay and 1080p will make a great system.
