Cube Stylus i7 probably isn't available any more as it's was discontinued a couple of years back but the superior version Cube Stylus i9 should be obtainable somewhere in EU (Brexit isn't done yet so you're still part of EU, right?). Just don't buy Surface, those are too expensive and I can't recommend spending that cash unless you'll use it because of brilliant software for work (example: Staffpad).

Note that I didn't see Caterpillar T20 in real world so while it could be an awsome choice if you're using it in "not friendly" surroundings, you should check with someone who has it before buying.

Yes I'm shilling for win10 based tablets. But why shouldn't I when they rock? ;)
