iPad screens often have a lot of glare and are difficult to read on bright days. I've never used another kind of tablet, but with the glass screens, I can't imagine they'd be much different.
Has Logos ever considered producing a dedicated e-reader/e-ink tablet just for Logos libraries (similar to a Kindle Paperwhite or their other ereaders)? I realize that would be a move from software into hardware, but you have a large enough library to justify it. I also realize there are some tablets available that use e-ink, but it's such a niche market, and they are prohibitively expensive.
Just curious.
