Like many of you I plan on buying a windows 8 tablet this Oct. 26th. Unfortunately Logos will not produce a win RT app until the popular of these tables reach a certain threshold. Which I cannot blame them. However, there is a new program in ALPHA release right now called Bluestacks that is a Android emulator for Windows. Install this on windows and you can install any of the apps from Android.
You can access Google Play and download them. I went to the forums here and downloaded the newest version of the Logos App and so far it works great!
