I thought all tablets have sealed batteries? I won't have a phone with non replaceable parts like batteries though or lacking internal storage, two of my gripes about apple. I despise planned obsolescence, when it comes to consumer devices, like cars, when I'm satisfied I tend to use it till it breaks, being the kind who hates waste and not being the kind of guy who always buys the latest and greatest. Until I converted to smartphones I used the same 10-year old Nokia phone, on its third battery, which was also dying, I needed three per day...realized it was time for a new phone. And like that Nokia, I want something I don't have to replace every two years. That is why I prefer android phones over apple, plus they are cheaper.
