I always have a tablet for specific work stuff.
Seen a few Surface computers, thought them a bit flimsy for work in the field. Been quite happy with a Motion Computing R12. Much better than other Motion tablets owned: M1200 and LE1600. The vintage 2002 M1200 is still alive, but that's about it.
But the R12 is not glider pilot friendly, as it actually costs money. This one was $2600 without a 4G modem. They're built for rugged field work. Sunlight visibility is good.
I disable the touch screen so it doesn't do anything odd while climbing around and holding it. It's been dropped, rained on and laughs about it. The pen works great. Personally wouldn't want to type on anything without a real keyboard though.
