I use an Alphasmart Neo to write my novels. It's incredibly easy to focus with such a machine. If it just had bigger storage capacity and a microSD slot I'd never consider another option.
My writer friend also loved the alphasmart stuff until his last one died and he was looking for something with a bigger screen. I gave him my old remarkable and he got himself a little fullsized bluetooth keyboard and he's as happy as a clam now. Every time we see each other he thanks me. Loves the epaper and extra screen real estate and claims it's easier to pack around than the alphasmart. (flatter, boxier, etc)
The Neo has small storage, and is divided into documents, which I believe take up a fixed amount each of that total storage. Any decent-sized novel is going to strain the storage of the Neo. Still, it's a great little distraction-free writing tool.
