I agree with the previous poster about gathering more info from the school about implementation of the iPad program. I would be concerned too about the screen time and gaming. It seems like that school has worked really well, and if you could be given reassurance that they have thought through the iPad program and addressed your concerns, that might be the best option.

Having said that, I am a devoted homeschooler. There are so many wonderful opportunities for hs'ers, both on and off-line. Socially, I am lucky. I am in the Philly area and there are two drop off programs for hs'ers in the area. Sort of like part-time school. My DD 10 goes there two days per week where she takes writing, local history, model UN, and Odyssey of the Mind. It really addresses her need to be with her friends. If you live in a major metro area, maybe there is something similar?

FWIW, I wanted a place like that so bad when I started homeschooling that I helped create the one where my dd goes. It can be done!
