Hey I am normally that impulsive as well and I have not read a book since. (To be fair I am working through a giant stack fo New Scientist magazines dad had that I wanted to read).
But the initial price was around $360 Australian and that has gone to $540 for the PRS 505 because of the fall of the Australian dollar.
If I want a reader now I'll have to defect and get a Bebook as I can get one delivered for $460. Doesn't look like a bad device and I REALLY want to read the rest of the book I had started
