Here's a screen shot of Greek, Roman and Byzantine Pottery at Ilion (Troia) on an iPad. This is in the default reader iBooks.
You can click through to the Flickr page to get the full-size image. This gives a sense of the dimensions of the iPad screen.
OK, lots of work to do to make the page layout better, but I will admit to thinking this is cool.
Some annoyances: This volume is co-edited with Billur Tekkök but only "S. Heath" is showing up at the top. The underlined links don't work. That's also the case in the Stanza ePub reader on my iPhone. Desktop ePub readers do follow links (or at least some of them do). I think they all should, regardless of device.
There will be more to say so stay tuned. The brief "take away" is that eReaders will be one channel for the distribution of archaeological data. I look forward to RadioSchack and the like selling color devices for somewhere between $79.00 and $179.00
