I can't afford it at the moment, but what I've played I've loved. Honestly, I think it'd hold my attention far longer than Wii Sports did. Just flying around is a blast. xD
My only complaint is that the island looks exactly like the first island level from Pilotwings 64. This annoys me because 1. it makes me realize how much I want a new Pilotwings, and 2. it reminds me how Nintendo is ignoring most of their franchises that could make excellent use of the Wii controls in favor of the Wii series (except for Mario Kart). Where's Mario Tennis, Mario Golf, Pilotwings, or Waverace? By this point in the GameCube's life, we had seen 3/4 of these franchise PLUS Mario Kart, Zelda, Super Mario, and the rest.
