Dear Alefor,
I found your contribution to be both insightful and informative, relative to the differences between Apple and enTourage and their updating/upgrade protocols.
I believe the "uniqueness" of the enTourage, the relative "newness" in the recent evolution of the "pad" platform in general, apart from the "tablet" platform, has yet to fully establish "universal" protocols that singularly "benefits" the device(s) "owner(s)/user(s)" as opposed to the corporate entities "interests" who make them available to us.
I would say, however, that the wide-ranging availability of Android-applicable APPS gives the enTourage "owner/user" applications (programs/usage) akin to upgrades/ "updates" / software that is in a constant flux of release we have the "immediacy" of access to.
I guess it comes down to "perception IS one's reality."
I believe I have strategized a number of uses for this most excellent enTourage eDGe device, even as additional uses are evolving, given the plethora of interests I am immersed in.
I did, however, want to acknowledge your "musings" as being quite interesting, succinct and germain to many others acquiring these devices.
