I thought I should post a note here about iGigBook under the AMI DuOS Android emulator, under Windows (
http://amiduos.com/). This is a viable iGigBook platform that I am now using for regular gigs, on an HP ENVY 15 x360 PC convertible notebook with a huge 15.6" display. There are a few issues, related to a) the mechanics of getting DuOS running on a given Windows platform, b) coming up with a good stand to hold the notebook (there are a few choices but standard tablet stands won't hold the big notebooks), and c) some differences/issues with the Android version of iGigBook, which are steadily being addressed. But all in all, and even though this is not an official supported iGigBook platform, DuOS under Windows is definitely worth considering if you need a large display capable of presenting two full-size pages side-by-side. It kicks the butt of every other Windows-based music reader that I have found.
