SD card storage and Android
"Probably the fact that Google, in their infinite wisdom, have decreed that being able to save to a device's external SD card (and thereby do useful work on it) is somehow a "security risk". The fact that the Android OS even has such a setting is to my mind idiotic; but to have it enabled by default, and locked so that the end user cannot correct it (short of rooting the device), makes less sense than deliberately trying for a Darwin Award. You couldn't make it up."
And I heartily agree with you.
My current device, a Huawei T1-701U mediapad allows me the luxury to use my SD-card as storage, but if I upgrade my OS on that, I will not have that luxury anymore.
That is the reason why I prefer a device with SD-card capability as you can store your data on the card. Device crashed/bricked solid? No fear, pop out the SD-card, pop it into another device and it is business as usual.
SD card getting full? No sweat, procure a bigger one, copy all data over from old to new, and continue as usual.
Any iThing? Sorry, you're out of luck. It is either upgrading (expensively) to any unit with larger internal storage or employing cloud storage (with additional $$$ expenses)
Oh, by the way, I'm not in the mood to, neither do I have the funds available to, pay for extra $$$ expenses for cloud storage just to enable me to store more private documents/pictures/etc in the cloud (aka somebody else's computer). Any beancounter worth his salt will tell you that unnecessary overheads will continue to eat at your bottom line.
So, give me a device with the ability to put all my apps and data on SD card, and I will use that product/device for a long time, thankyouverymuch.
