I want to just know as alternative the best Android tablet on which Logos could be utilized.
I use Samsung Tablet and it works well. Others say Nexus is best but I dont like that there is no external storage slot. So what the best tablet is depends on your individual needs
Any recent tablet by a major name manufacturer should work well, e.g. Samsung, Acer, Lenovo, etc. I would avoid Pantech and similar low end tablets, because their screens are mostly junk. If you want an 7-8" tablet, look for minimum resolution of 1280x800. If you want 10.1" tablet, look for one with higher resolution than 1280x800 so you get crisp text. To me, anything above ~180ppi is great. Below 150ppi is fuzzy, e.g. iPad 1 & 2. Here's a tool to help you figure ppi/pixel density: http://pixeldensitycalculator.com/.
If you're going to download tons of books, look for one with SD card or even better get one with more main memory, but for most people 16GB will be plenty. Unless you download everything in Logos plus try to store other large apps, movies, music on the tablet.
Also go for a recent version of Android. Older versions may or may not get updated and features stop working on older tablets as time goes on, e.g. Google releases next version of Android but it doesn't roll out to 2-3 year old devices.
My preference to Android is based on the fonts I want to use I have ipad air ,but I am not able to read the word documents unless I send them by e-mail as PDF.I am going to be able to read ,but not to edit.What I want to do is to prepare on Desktop and synchronize it using dropbox. If the price allows me I need a bigger size Android tablet ,on which I can run my Logos app and read my word documents.Everthing is possible on the surface pro,but it is not affordable.
I use a Nook HD+. With it being an e-reader, the ability to get the Kindle Android app and the LOGOS, Vyrso, and Faithlife apps, I use it as my goto device when I do not have my Windows 8 laptop. Its biggest limitation is the 8.9" screen - I would prefer more screen space.

You can do this with Word documents when syncing to iPad
Sync using Dropbox and then open in Pages.
