Apart from looking for the best April Fools articles this week, we found a great piece from Wil Shipley about why the Mac App Store needs paid upgrades, Farhad Manjoo’s explication of Google’s newfound focus at Slate, and a solid rundown of iPad charging issues by Dan Frakes over at Macworld. Plus, listen in as Adam talks to the Diablo Valley Mac User Group on MacVoicesTV.
 -- Wil Shipley of Delicious Monster feels the pain when he can’t sell a paid upgrade to his software through the Mac App Store, and he has sales graphs and logic to prove why Apple’s refusal to allow paid upgrades is bad for both developers and users. When will Apple realize this?
 -- The third-generation iPad features heavily in Adam’s virtual Diablo Valley Mac User Group meeting with MacVoicesTV host Chuck Joiner, but other topics include the extent to which Apple should be held accountable for mistakes, Apple’s quarterly dividend and stock buy-back program, and a wide variety of answers to audience questions.
 -- Over at Slate, Farhad Manjoo has an insightful piece that looks at how Google has learned to focus its efforts on seven key businesses: search, advertising, social networking, Android, Chrome, YouTube, and local mobile commerce. We just hope they don’t give up on the self-driving car!
 -- In this article at Macworld, now updated for the third-generation iPad, Dan Frakes runs down all the possibilities for charging an iPad — wall chargers, high-power USB ports, and low-power USB ports. If your iPad takes longer to charge than you think it should, make sure you’re using the right port and giving it sufficient time.
