A week of sales in Android's Market at $1.60 either went so well for 8pen that they could afford to give it away for free... or it was their only option due to lack of downloads.
I had a very brief play with it last week after I ran into Gizmodo reader Adrian on the train. Tracing various figure-8s on his Hero's screen wasn't the most intuitive way to type, I felt - and in fact, I struggled to string a single word together. Maybe a longer stab at it would've been more successful - some of you downloaded it last week and seemed to like it, but most said they wouldn't replace Swype or SwiftKey with it.
Anyway, it's now free (and includes a long list of updates such as voice input, dictionary support and themes), so if you were hemming and hawing over paying a buck sixty for the app, have a go and let us know in the comments below. It works on any Android phone running 1.6 or higher. [8pen via Phandroid via EuroDroid]
