So I bought a Slate 500 last week.
Nice bit o' kit
The only issues I have with it are screen brightness in direct sun and the lack of hard keys (I'm learning)
that is my 6 year old Samsung Q1 ultra has both hard keys and brightness levels acceptable for the beach on a sunny day.
The size is right in between my old tablets.
Samsung Q1 Ultra (2005) 7" - HP Slate 500 (2011)8.9" on dock - HP TC1100 (2003) 10.1" on keyboard
The thin Slate 500 is nice to hold, but I prefer the rounded edges of the others, for ergonomic comfort.
And to get an idea of relative full brightness here is the HP next to the old (but brighter) Samsung LED screen. (exposure set on brightest display to avoid dynamic clipping)
...I never found the brightness spec for the Slate. ...280_nits?
Redbeard, hopefully you've found the Pen/touch input settings by now. You have 4 options there to control pen or finger, to avoid palm interference.
Oh, and a small tip, that I just discovered, the screen rotation can be locked by sliding up the power button.
Now I need to figure out a car charger...
