I have Pocket e-Sword on my HTC HD2 phone and use it as the Bible(s) I always have with me. I chose a Windows phone because as well as e-Sword, it runs Microsoft Word, Excel and PowerPoint - all useful when overseas on mission work. I carry my NIV Study Bible for general use overseas, but the Bibles and Strongs concordance on Pocket e-Sword are invaluable for study and discussions - although I'd love to have AMP and the NASB and concordance on Pocket e-Sword.
If Android could run Word, Excel and PowerPoint I would gladly switch to MySword! Until then it is so convenient to have Bibles and Office in one device.
