I am very excited! I recently upgraded my phone to the Epic Touch 4g (Samsung Galaxy II) and my tablet to an Asus (Google) Nexus 7, just in time for Notes and Markup support for the Android version of Logos.
I have been using Libronix (Logos 3) on my Netbook in my Precept classes because the number of Markups I have makes Logos 4 too slow on a low end system. I like the Netbook because of the battery life and the size. So the idea I could switch to a tablet (and a bluetooth keyboard) and start using Logos 4 full time is very appealing.
Warning: Markups and Notes are still in Beta. So far at least, you need an active internet connection for these features, and if you use as many Notes and Markups as me, it is kinda slow to pull up everything… I really recommend you turn off Notes under Settings on a phone.
