Writing on an ereader.

So I am currently working on a new book, and I am writing it on an ereader. Whether it will ever be read on an ereader is for others to decide. But it is definitely being written on one.
As you may or may not know, I write on the subway. At one time this involved getting on the train at the second stop on the F line (so many seats, so much time) opening a journal, uncapping my pen, and letting my shaky hand scratch indecipherable marks on the page. Years pass, times and needs change, agents use epithets to describe your process, and soon enough I was fighting for seats at a different station (still the F, but the train is “more crowded” i.e. Full) and using a laptop (goodbye journal, goodbye chicken scratches, goodbye months having to transcribe with a netbook on one knee, a journal on the other). But the fight wasn’t easily won. I often couldn’t get a seat and my writing time was thin and getting thinner.
Enter the Nook Color. Just a few weeks ago the Nook Color firmware was updated. The ereader now has built in email, an app store, and online browsing. After a visit to a Barnes and Noble and a test run on their floor model I went home and googled “word processing Nook.” Guess what. There’s an app for that. Low and behold some eager beaver has written an app that allows for creating and editing Word documents. It even syncs with DropBox or Google Documents. I bought one, installed the update to the firmware and realized with a grin that the Nook Color is basically a tablet pc.
Now I don’t worry about getting a seat. I can stand anywhere and work. My thumbs do my talking for me, and I’m back to getting my words in daily. Is it perfect? No. I would like a healthier autocorrect (how about a period when I double space?) and it would be nice if it remembered how large I like the font to appear, but no system is perfect. You only have to look at my handwritten and untranscribed third novel for proof of that.
