Query: Tungsten E covers

The Tungsten E comes with a vinyl screen cover which wears out after 3 months of frequent use. Unfortunately, Palm does not make replacements available. The cases offered do not allow the Tungsten E to be placed into an hot-sync cradle for information updates for MercuryMD or Patient Keeper systems. Thus, if you a physician contemplating use of these systems, I would NOT recommend a Tungsten E even though it is otherwise a very nice PDA
