I recently re-acquainted myself with hacker keyboard, but decided to go back to Touchpal for 2 reasons:
1- the volume of the key clicks in hacker is way too loud, and turning the A500 down to just above total mute doesn't make it quiet enough. I like the clicking, but not that loud.
2- Hacker has smaller keys, so I find myself making more mistakes. I think Touchpal has more options when it comes to sizing the keys themselves.
The one thing I don't like about Touchpal, which hacker mercifully did away with for me, is the "keyboard" key just left of the A key. I hit that way too often while typing, and would love to disable it (I never use it intentionally anyway), but I don't know how. So I didn't miss that, for sure.
The only issues I've had with Thor JB V23 recently may or may not be hardware related. Sometimes I can't get the power button to light the display. A few times I had to hold it and reboot, being the only option.
Aside from that, and the aforementioned browser instabilities, it is working OK.
