Well I took the plunge and ordered an Oasis as well, partly based on the feedback in this thread. I want to compare it to the Forma I just got, and decide which one is the most compelling for my use. Not that hard to re-sell or gift the one I end up not using. Previously I had avoided the Oasis due to concerns about the battery I had heard here at MR, plus the fact it's a smaller screen than the Forma. But after handling one in a local store, I realized it's a really compelling reader, and despite the smaller screen, it can compete head-to-head with the Forma in almost every other way other than screen size. It sounds like the battery life for most folks has been good-to-go if you set your expectations based on Amazon's predicted 21 hours of usage.
