Lets say true, Chumbi is predecessor of Sony HIDC10 Dash Personal Internet Viewer (and old model HIDB7 without backup battery, oldest Wi-Fi connectivity, slowest CPU, buggy firmware).
The big advantage of Sony Dash vas Dash app Store (like Apple App Store, closed in Jun 2017, new registration not able from 2014.), where You may find weather apps, and apps for YouTube, ESPN, Pandora, Slacker, online music radio, and other well-known news web resources, Google Gmail, etc. Not bad for 2000 yeah?
But the are also a lot of problems: buggy software (even a new version), hardware overheating and device freezing problem, troubles with app installing due bad server-side software response, too much losing Wi-Fi connectivity, and overall device quality was vary from good to buggy.
The Dash sound was 50/50 because device positioning like "personal alarm clock" extendable by third-party apps. The screen has lack of sensitivity. And software response time was really awful, especially if compare to Your first iPhone.
