One the main features of the new DSi is the DSiware. It's basically just a smaller version of the Wiiware and Nintendo's first push in Portable Online Distribution. But so far it has failed to fulfill it's potential in the West, especially considering the plethora of titles available in Japan or other potential titles.
The launch titles weren't too bad(in Europe at least) in my opinion. Warioware: Snapped is fun but is certainly lacking. Pyoro and Paper Plane are nice little games and are alright for the price. The two Artstyle Games were the best games available though. Well designed, appealing puzzlers and also a free browser.
However since then the updates have most been lacklustre with only Real Football 2009(an admittedly good update considering it's a full DS game) and Dr Mario worth looking at. I think if they don't improve the updates that people will eventually stop checking and only going on the store when they hear about great games.
The best, most viable update in my opinion was Dr Mario and the first Magic Made Fun game/app. It offered a classic Nintendo puzzler which a lot of people are familar with, it also sports a funk art style for the characters. It also offered something that won't be as popular but might intrigue some people. This is the type of update I would like to see.
The main problem Nintendo faces is that whilst they have quite a few games/apps lined up they're not localised or the third parties are still sorting it out this is why I thought of some things Nintendo can do to get momentum going for the DSi and make sure they enough software for future releases:

Push Square: "Yakuza Kiwami 3 & Dark Ties is one hell of a package. Taken purely as an expanded remake, it's an absolute blast for fans both old and new — but questionable changes to the story and its cast will inevitably stain the experience for plenty of people.
It's such a shame that these unforced errors muddy the waters, because we think Kiwami 3 is probably RGG Studio's best remake to date — and one of the strongest titles in the series with regards to gameplay."
A graphics comparison highlights performance and visual differences for Monster Hunter Stories 3 on Switch 2, PS5, and Xbox Series S.

The original entry in Ubisoft's platformer series, Rayman, is set to receive an HD remaster, according to the series creator.
Big Rayman fan, but hopefully they add some cool new things for those of us that already beat this on the PSX/PC/Saturn.
HAHA! This week's European DSiware update has been the best ever with an 800 point game(Pop Superstar) and a 500 points game, that happens to be the best DSiware game yet. PiCOPiCT.
This is the type of update I want to see. Now all we need is Mighty Flip Champs, Moving Notepad and Dragon Quest Wars!
