I enjoy having a Bible program on my computer that does not require me to be online, but I must admit that many of them are expensive. Here is another free Bible study program based on the ESV which the main drawback is that you must be online.
When logged in you can highlight words or verses, underline, or place a ribbon at verses. Notes can be added to Scripture passages and there are several reading plans available. This all includes the nice feature of having an audio available for listening to the Bible.
While nothing will ever replace actually holding and reading a Bible, there are still many advantages to using a Bible program at times, especially a free one.
