I have an E5.00-2 that I own as a backup device. It's usually turned off somewhere and in a drawer or in a console in the car for emergency use or if I want to use another phone number.
But I have used the E5 enough to know that the screen would drive me up the wall if I had to use it as an everyday device. It'd be great if you're only typing and only indoors. But it'll be very weak if people are always sending you pictures or if you have to do something in the sunlight.
The screen would kill the E5 for me as an everyday, regular device, for whatever one person's opinion is worth.
(Great, sturdy little thing for the money, though. Gotta give it that.)
