That's right, Money will not be sold on store shelves any more. The only place to get Money is online (it's unclear whether it will be through MS only, or a variety of places online; what is clear is that the packaged, shrink-wrapped package will no longer be sold).
This is a step in the right direction. The trend for digital downloads is way up (Microsoft reports that sales of the digital version of Money equaled the packaged version, up from a 1:3 ratio the year before), it saves Microsoft a ton of money, not just in packaging but in picking up the software that doesn't sell (and then what?).
Plus, software in a package is so yesterday. For the consumer, it's just much more convenient to download and buy: No trips to the store, no waiting for the mail, no boxes to throw away, etc.
One tip for digital downloads: Make a backup right away and store it on disk (CD or DVD). DO NOT BUY THE BACKUP THAT THE VENDOR OFFERS. Number one, it's a waste of money. You CAN do it yourself. Second, you're kind of defeating the purpose of the digital download in that the vendor is still sending a physical product through the mail (or UPS, FedEx, etc.).
Is Quicken next?
