I just wanted to bump this post up in case anyone missed what Rich had mentioned earlier. JTS (
http://johntillersoftware.com/) recently released a pair of tablet-based (iOS and Android) games called "Panzer Campaigns" and "Civil War Battles" which both have a similar interface to Squad Battles. Free demo versions are available for download to give them a try.
I'd suggest people try these out if they are "jonesing" for a tablet version of SB. Plus, the more interest and support JTS receive on these initial tablet-based projects will likely encourage them further towards getting SB ported as well.
