As Dan Frommer of the Silicon Valley Insider  points out, The WSJ has reported that Google is building a store for Google Apps - the business version of Gmail, Docs, Spreadsheets, and the Calendar (all of which I use in my practice). The Google Apps Store would allow customers to buy add-ons only if and when needed to extend their basic Google Apps environment without having to buy the whole enchilada. Apparently Microsoft still has not gotten the memo however, as its Office 2010 (which I am now beta-testing) is still bloated, slow, and crash-prone in the proud MS tradition. This as Google tries to disrupt several Microsoft businesses, including its Office and Windows giants, and its Exchange email business. Google could announce the App Store as soon as March, the WSJ's Jessica Vascellaro says. Like the App Stores flourishing in the mobile industry, Google could collect a cut from sales while passing the majority of revenue along to developers.
