I made a Wii U Review Video
Good review. One thing tho- I think Nintendo recommends using an HD with its own power source- some people have used a Y Cable for USB memory sticks and i think the SD card is pretty much for transferring your Wii data (or at least that's the only function i can think it can be used for if it is indeed not recommended to use as storage).
Only other minor thing is that i don't think the lack of a chat system deserves a full point deduction. For me, it's not a big deal at all, but I can see that as an issue for some. Though I do see the lack of third party support and a few other small things adding up to your score (range of game pad, life of gamepad battery etc.). As you kind of suggest, however, if you like the first party games & exclusives and just kind of want to sample some of the other games (like me), this is a great console to own.
So, as i rated above, i think a 9.5 is about right, with my main complaint being that we won't see many third party games to speak of for the next year at least; however, there are some great games in the pipeline after E3 and enough to keep you busy until then.
