I own 2 tablets and the missus has told me I need to donate one to the father-in-law for Xmas. But I cannot decide which one.

I have a rooted 32GB HP Touchpad with Dual-boot of WebOS and KitKat that comes with the official HP Case and induction charge dock. No card slot for storage upgrade.

I also have an unrooted Acer Iconia A500 on Ice Cream Sandwich with official case that is incapable of charging via USB, is only 16GB, but is of a slightly higher specification. It also sports a mini HDMI out, USB port and SD card slot.

Both tablets are of about the same age (Early 2011).

THE COMPARISON

The father-in-law is only going to be surfing Facebook Selling pages and eBay maybe once or twice a week, so I want to keep the better option for myself (of course).
Which should I give to my father-in-law and why?
