Nice project & explanation.

I can see myself expanding on this (maybe even re-hashing your library essentially) running:

1. a Calendar,

2. next to a Stock Ticker,

3. next to a Financial accounts (i.e. all current asset) combined with Financial goals.

I've been thinking about the third one for a while. E-Ink / a simple, low power, monochromatic screen (similar to Amazon Kindle eReader) would be a good choice.
