I'm not sure how many people are aware, but there are now dirt-cheap Windows 8.1 Tablets out there at Microcenter. I don't know how well some of these (especially the 1 GB RAM versions) would run full Logos 6.0; however, at sub-$100 price points, I'm again debating on getting a Windows 8.1 Tablet rather than an Android. (I've got a Microsoft SurfacePro, but I don't like carrying it everywhere--it's too pricy to spill coffee on!
)
If these little tablets pick up, combined with Windows 10 and universal apps, I think Logos might need to seriously re-consider a more robust touch-enabled version. Windows might yet make decent penetration in the Tablet/Phone world.
