Much like Wii points, 100 DSiWare points will equal one dollar. The downloadable apps will include titles such as WarioWare Snapped, which uses the camera to carry out the mini-games, and Code 10, a Sudoku-like number game. Prices have yet to be revealed for these games specifically, but they will fall within the $0-$8+ range. [Nintendo DSi]

The obvious fear for most users buying ESD products is not having the software on physical media to re-install the product at a later time. Microsoft Store solves this by letting you re-download the product until mainstream support for the product ends. Typically this is 5 years after the product is released. You always have the option of copying the downloaded products to physical media if you want to have it available longer than the mainstream support lifetime.

When I buy a copy of Windows (or anything else), I expect to keep it forever—what if my older PC borks out and my cheap burned disc has degraded? Essentially taking away something I bought is no good, after five years or hell, ten years. On Steam, stuff is there to download forever, like a digital vault, which would make people feel safer about going all-digital. Also, when it comes to your whole OS, it just feels safer to have a hard copy in that lovely swinging plastic box. Updated post for clarity. [Microsoft Store via Trevin Chow via ZDNet]
