Hearing about the Chumby when it was released it seemed too costly. When Best Buy discounted their last inventory of Infocasts in about 2009 I purchased two (3.5 and 8 for about $100 combined) and use them just about every day. It was easy to load the Chumby software onto the Infocasts when Chumby failed, so they operate as Chumbies; the hardware is a bit different but the user experience isn't significantly different.
Last winter the Infocast 3.5 we use as an alarm clock failed. I couldn't find another Chumby or Infocast for what seemed a fair price, but $30 got me a Sony Dash on Amazon. Different hardware, can be converted to the same Chumby software for the same Chumby experience. The Dash screen seems a bit better, than the Infocast, but it's not a glaring difference.
It's going to be harder and harder to justify the purchase price if, as seems inevitable, the apps continue to fail over time. Only a few in each category still work. But Pandora still works on the Infocast, there are various clock apps, one or two weather apps, and a game or two, which is all I'm expecting at this point so I'm happy.
