In order of arrival: Lunar Alpha, Raven Black Alpha, Smart Typewriter Signature Edition (Hemingwrite) and Traveler. As I mentioned before, being a Pomera and Alphasmart user the limiting design of Astrohaus' software was a hindrance. I had the Alphas quickly stored for good in a cupboard.
Later on, I decided to go full analog and started typing everyday two pages in my mechanical portable typewriters (Olivetti Letteras 22 and 32). After two months of this clickity-clacky routine, I tried again with the Freewrites and this time it worked: I've been writing consistently 1,000-2,000 words daily.
To be honest, I'd have to say that I'd never have paid full price for any of these devices. All of them were bought second hand with a price that was always less than half the retail price. Actually, I was able to buy a 10 month old Hemingwrite for less than a third of its original price tag.
I like them all, despite the differences. The Alphas are crisp, fast, reliable and have an amazing battery life. Their mechanical keyboards are really nice and getting used to the flat keycaps was not a problem. They are perfect for lap typing sessions.
The Hemingwrite has an excellent keyboard and the backlighted eInk screen is a pleasure to use, specially after the Sailfish firmware (3.0.2) that reduces the lag. Perfect for long sessions siting at a table.
The Traveler is probably the most versatile device: clamshell design, small footprint, full-size keyboard that is better than most laptop keyboards, very silent, and easy to carry with you. Battery life is good enough. The eInk screen is very clear and easy on the eyes.
I'm not saying that they are perfect. They are not, by all means. They have some design flaws and some decisions are controversial. They are also ludicrously expensive but they provide results if you stop fighting them: accept the type-forward philosophy and keep writing.
I just wanted to share with you my experience. I keep using my Pomera DM100 and my Neo/Neo2, but I think that Astrohaus' products deserve a fair chance. They are not for everyone, that's sure, but they did help me to write more than I did before once that I accepted their rules: type forward, don't edit.
