My wife has been wheelchair bound for the last ten or so years, about six months ago she had a knee replacement but has been unwilling to get out of her power chair. She'd rather ride than walk. Plus she has a couple of inches of leg length discrepancy.
I ordered a MiniPro as an incentive for her to get more mobile (I wanted one too
). The MP hasn't arrived yet, so I'm not sure if it will be useful for her, but your right, no matter what the COOL VALUE can't be denied.
