Thanks for the great thoughts. On a second thought, I decide not to bother. The reason why I want to install Good is that I thought I could transfer the email to the eink for eye ease reading.
With the understanding that only web browser has the ability to print such contents to the eink page, I see no reason to use eDGe for Good. I have already have an android phone that I can do the same reading.
Thanks for the suggestion anyway.
