Any moisture is a bad thing if the drop gets to the wrong spot. Your post looks like you want something unfettered from Apple or Amazon but those are really great products. Take another look at iPads and Amazon Fire tablets.
i am searching for a tablet that i would use mainly at home read manga,books, use youtube, watch movies and tv series and i would also love if i could also draw in it
here are the things that is most +necessary or -not needed for me:
+wi-fi
+it has to have a decent-good resolution
+it has to be one of the bigger ones(since i have bad eyes and its sometimes hard to read small letters)
+budget is 300€ (can stretch) i will not buy used stuff
+cant break in a year or 2 without reason ( i care for my things and i rarely drop them so my things don't have to be from iron but when they brake simply from using it sucks)
-no need to be good for gaming,no need for any camera, mic, does not matter how fat it is
-i'm fine with 16-32gb of memory (may even go with 8gb if necessary)
-no need to last long without recharge(since ill mainly use it at home and if i will use it outside ill use my powerbank thingie to recharge )
?sound does not matter much since i will use headphones 95% of the time
?i would love if i could draw/paint (i mean that it would have that feature where the stronger u press while drawing the thicker the lines are)
?would be better if i could insert memory card (or whatever its called) in case my needs changes
? i may drop a little of liquid on it so id love if it would not break from a little touch of coffee or something like that (not planning to drop it in a pool tho)
