Going back to the subject, rather than a iOS / Android willy waving contest.
I have to confess that, although I've considered one, I have never used an android device with SD as I'm sure, at the time I subscribed to SD, it was a 'lesser version' available on Android. It may have changed now, so happy to be corrected on that one!
I'm currently using my wife's old Ipad 2 cellular, which must be getting on for seven or eight years old, and it works fine - haven't experienced any overheating issues. Previously, I used an Ipad Mini with a Garmin Glo GPS, and it was the Glo which kept quitting due to overheating, as it usually sat on the coaming in full view of the sun. Popping it out of the sun for a couple of minutes revived it, though, and I found it worked just as well sitting on the back seat.
My point is - eventually - that there are loads of second hand ipad 2's about on online auction sites, which will be the same kind of money as a new Android tablet.
