Original iPad being junk? There's tons still in service. As a matter of fact, I'd imagine most who upgraded to the 2 or 3 did so due to additional features (camera, Retina), not the RAM.
Also, how do I upgrade the RAM in a Galaxy Tab or a Kindle Fire? I think the lack of upgradability is endemic to the tablet form-factor.
Main positives are for ability to remove the back side and use of Phillips screws: big pluses. However, primary iPad issues: glued on front glass, RAM, persistent storage: all true for Kindle as well.
