Just a minor note - while messing around, I was looking around on my black Wii to see if I could download any of those demo titles that Nintendo put up some time ago (Pokémon Rumble, etc.). Couldn't find them anywhere.
Decided to try a different tactic... Booted up the white Wii. Went into my downloads history, thinking I could select the title and choose to gift it from there. No luck - the demos were no longer in my "Titles You've Dowloaded" section. Shucks. So, I went into my "Account Activity" section... sure enough, it shows I've downloaded the demos. Clicked on one to see if it'd let me re-download and/or gift it... no go! Got an error message saying the title was no longer available and that I couldn't re-download it.
Now, the demo still works (via SD card), and, right now, as far as I know, only demo titles cannot be re-downloaded. But this is an icky precedent. Wonder if there will come a day when Nintendo won't let us re-download titles we've purchased? Good thing I've got them saved on my SD card... so long as I don't have to send my Wii in and get a different one back, I'm all good.
