Launch Wii U Deluxe here. No problems downloading over WiFi and updating; worked like a charm on the first try. After the reboot about 2/3 of the operations I tried (mostly opening/closing various stuff) was much much faster. This is how the Wii U should have operated on Day 1... but i'm not disappointed, I'm just happy they are taking it seriously and addressing it
My Wii U suddenly became a lot more fun to use now that I don't feel like everything takes 20 seconds to open and close. A++ :3
Bring on that Summer update and most of all... bring on more games!
Wow what a great week for the wii U (relatively speaking)... kirby! wii u spring update! VC (disappointing launch lineup but yeah)! and mobile miiverse
