This September, there will finally be a new reason to log onto DSiWare. No, there isn't a new myNotebook release (this time). Rather, you should log onto DSi Store this September to download a free copy of the strange, eccentric, and super cool game, Zelda: Four Swords.
A local multiplayer- based cooperative offering released as a pack in to the GBA port of A Link To The Past, Zelda: Four Swords was a really neat multiplayer offering that still worked around the standard Zelda mechanics. And now, you'll be be able to download the full game for free this September, as part of Zelda's 25th anniversary.
Is a free game enough for you to log onto DSiWare? It is for me.
