My comment on one of these:
But 'people who lack the upper body strength to read a standard-sized novel' is a kind of specialized market.
… but there are a lot of us out there. In my case my reading-disability is not upper body strength but manual pain (hands/wrists/fingers) and I can manage to hold my Sony Reader Pocket (small like the new kindles) for a while or lean it on my pillow (or read on my mac) but can only hold a paperback for a minute or two and a hardback? Never.
So, for me personally, eBooks and web-fiction enable me to read fiction. At all. As someone who used to devour more than one paperback per day as a kid (and usually adult/non-kids' fiction at that) I finally feel like I am coming home.
As to price, as someone who is an undischarged bankrupt on benefits and DLA (the UK equivalent of unemployment and disability/SSI/SSDI etc.) free would be great but I know you authors need to eat and so I tip (crowdfunding FTW) when I can and buy as many eBooks as I can.
Just my 2p.
