Query: Extremely disappointing

I have owned the Edge for two years now, and I continue to be disappointed with it as time goes on. The fact that it has been discontinued speaks for itself. This [pricey] unit was marketed as state-of-the-art at its inception, but basically it is a glorified address book. And its exterior design has proved not to be so great - the flip cover is inconvienent, the hard case is not a protection, the springboard module adapter system simply does not work, and the battery has to be recharged every day. With the recent announcement of the re-merger of Palm and Handspring, one wonders whether the entire Handspring line has been one of the most colossal cons of the electronic world.
