According to a passing mention in the Wall Street Journal, the Android Market could start accepting for-pay apps as early as this week. We've been expecting such a development to hit this quarter, and it makes sense with that RC33 update in the bag. Unfortunately, this WSJ quote -- pulled a piece on Microsoft's mobile strategy -- is all we've got to go on at the moment. Either way, paid apps are obviously an inevitability, and that financial incentive could be a major boost to the Android ecosystem... or the harbinger or farting apps.
