Yeah, I hear you. Really, aside from the options screen I don't have much of a problem with it. Now that I think about it, I kind of shudder to think of what the games menu will look like if a PS3 user were to go on a PSN shopping spree. I know from experience that it can get a little annoying with a PSP and an 8GB memory stick (because, honestly, screw UMD and not having any battery life on my gen 1 PSP; the first thing I do is rip those suckers), I'd hate to think about what you can do with a 160-250GB hard drive.
The Wii interface is fine, but it does have one extremely major flaw: the inability to use GameCube controllers to traverse the menu. Considering I use it more as a GameCube than a Wii, the lack of that feature is insanely annoying. It might have been resolved in one of Nintendo's futile attempts to defeat softmodding, who knows...I hardly use the thing anymore. :s
