From Android to Windows Phone – A decision of decisions

Yesterday, i decided to buy a new phone for my work.
I owned several HTC One/OneX and others in the past, some with custom Mods, some without. I always paid the 600bux for the “newest” phone because it was “necessary” to get the best performance. Well, atleast i thought it was. It was that time, when the first quad core Smartphones came out, and everyone was hyped for it to be the feature, And yeah 1GB Ram ofc, more than my first PC had!
The only thing which bothered me was that you can’t exchange the battery pack. Adding a SD Card worked, but no replaceable Battery Pack. I feared, my batterys would die after 3 years and i would need a new smartphone. But nowadays smartphones taught me one thing:
If your smartphone lasts 3 years, let it die in peace, cause usually you can be happy they last more than a year.
