Sure, if it's in the budget. Triple the cost of a top end Android tablet and double an iPad. And if the display is any good. I don't know what kind of panel it, or other similar tablets have. Screen calibration? You have access to colour temperature, brightness and contrast controls? You have the ability to use a measurement tool like the Spyder or ColoMunki? Or is it a built-in, automated process that really isn't a true calibration and profiling? My understanding is it's the latter.
The display on the Samsung Slate is excellent.
It runs windows so you can use color calibration tools. I use my Datacolor Spyder Pro calibrator.
What was quite surprising is how little the screen color is modified to obtain calibration.
It also has hardware to create an ad hoc wifi network letting me use it for wireless tethering
on location. I also run Lightroom to do preview processing automatically running a saved processing preset
pretty much in real time.
