Hi Guys! I'm an architecture student in Melbourne, Australia and I want to buy a tablet with a keyboard and pen. I'd prefer a nice screen but it's not important because it's more important I have security. So I am thinking of a Chromebook with a tablet screen (one with a pen?) and a fixed keyboard OR the IPP with keyboard OR a Tablet S Pro from Samsung (you can use a pen?). What do you suggest? 10-12 inches is OK, but it's got to have a secure keyboard and I'd prefer no bluetooth because security is important. I want to be able to view plans but not to do any 3D CAD just to read documents, Kindle and view photos and perhaps draw in 2D. Thanks.
