I use an ereader a lot. They have glaring lacks that nobody seems to have addressed:

1. Two page layout. This gives you more context when reading.

2. Imperfect printing. Older books have imperfect impressions of letters.

3. Tan colored background, which varies across the page and from page to page. Grey is so sterile.

4. Cannot stick a thumb on a page and flip forward and backward with your other thumb.
