Depends on the user. A user who has exacting requirements will have the better experience if he can make the tablet do exactly what he wants.
A user who has no special requirements is better off conforming to what someone else thought up.
Imagine how useless a PC would be, if it could only do what someone else's "app" was designed to do.
Hackability defintely puts me in the Android camp.
Its not really removed, if your device doesn't conform to the specs for the OS version Google won't let you have their apps (their apps are closed sourced and copyrighted and not part of Android).
If the Fire is using Android 2.2 for instance it must have bluetooth and GPS to name two things (why? Because that's the rule the made back then, and they are not going to go back and change it now)
No Google should just continue doing what they are doing now. Device which don't comply with certain rules don't get access to the Google apps (which have never been open source and never will be) - you get a certain assurance of hardware quality if you get a device which has the Google market on it.
This would disappear if they allowed any Android device (Hey, I've compiled Android for my toothbrush!) got the market.
normal people who don't hack or root won't really care.
The tiny minority of nerds who do care can do it, and it just adds to the saleability
The whole purpose of Android is open system - the antithesis of iPad iOS - supposedly totally closed. Eventually (if not already) there will be more Android devices out there than iOS, but who will have the better end to end user experience? And will that matter more than an open system?
if in the end someone would hack the system as the company has provide the source code then why not company itself provide these basic facilities which make device more appealing....don't understand the logic behind such things.
This is not a Android hack, its adding android market back which was removed as part of customization by Amazon.
And I feel allowing customization is the most attractive feature of Android where each seller can create its own market.
I think in this case its threat to Amazon and not to Google. Amazon lost the control over market place.
