glen, I find the larger edge the perfect size for handwriting. I don't have the PE, but I have a 4.5 inch tablet that I also write on and if being able to do lots of handwriting while stationary (even if on a train/plane) is more important than keeping on hand at all times and whipping out while standing in line or walking down the street, I'd go for the larger one, too.

Also, I don't know whether it's just the difference in the owners of each device, but most PE owners mention a "slight lag" in writing (ink shows up slightly after the actual stylus stroke) and most edge owners barely refer to lag at all. It could just be that us old-timers have gone through a few software updates and are now quite happy with the speed of the e-ink, whereas PE owners are newer and perceive what we're quite happy with as a slight lag. Maybe boris could weigh in on whether the PE is a bit laggier than the EE, since that's just the impression I get from what various people report.

Still every now and then I want the smaller version, just for fun, but it's hard to justify since I already have a smaller handwriting tablet.
