I was going to go with the 32 gig but I rarely even get close to capacity so I decided to just get into the the door with a 16. The majority of stuff on it is music and I sync nightly.
Wii U is intriguing to me but I'm done being an early adopter for gaming consoles. Sad PS3/PSP/Vita/Wii launch periods have finally made me realize that I have a sickness.
I need the extra space for photos and videos. Honestly 32 probably isn't enough (those HD videos go through 32 gigs fast) but 64 is still too expensive. I was kind of hoping that 32 became standard this gen.
Honestly I barely have any interest in any of the Wii U games at launch nor have I been following it that closely, but 300 bucks and no memory card makes it sound pretty cheap to me and I am sucker for console launches. I have really fond memories of the N64, PS2, GC, PS3, and Wii launches.
I was very late to the DS and 3DS and never jumped in on the PSP or Vita (so far no games really warranted it, and two handhelds seems too much for a man as old as me).
I understand not jumping in on launch though. It is a poor choice both money wise and for games to play. If you want the most for you buck wait 1-2 years before jumping in. But man you seem to miss out on the best stuff if you want that long.
If you are a real gamer this past year and the next two should be getting you really excited. Two handheld launches followed by a Nintendo and then Sony/MS launch. So many new consoles in such a short period of time.
