tesral - you should be able to view those maps on the tablet (I just did on my phone), but editing I would probably stick with a laptop too. Also check out "Skitch" for your laptop and tablet. I use Skitch quite often for grabbing just a section of a screenshot plus can add notes and arrows.
Currently we are a group of 5 or 6 depending on the night.
Started off playing D&D back in the 80's until Robotech came out in '86. Have sat in at few games of AD&D, but mostly GM'd a Robotech game for the past 20 years with a few years off inbetween. I started GM'ing with Rifts in '06 to '08, but needed a break.
I've been playing around with a mish mosh type of game for a chuckle.....A mix of TMNT, Robotech, and CoC. It would be a one time run for a filler and lots of laughs.
I also ride Enduro's on a dirtbike which cuts into my Sunday gaming time during the season.
