Super tablet very fine and light

For my part, I bought in 32GB version (not that Amazon has not yet noted) to replace my old Asus Transformer Prime, which was beginning to acknowledge the scope of age.
I am fully satisfied with this Sony tablet (display, responsiveness, lightness ...).
The only complaint I could make would be about making caches tablet waterproof.
Not having planned to use it under water, it is rather a strain.
I (for work) a smartphone Xperia go, and unfortunately the tab holding the cover of the USB plug broke after a year, making lose all tightness.
I fear the same thing with this tablet, so I think investing in a charging cradle, which will no longer require the manipulation of the USB cover.
