For work I have an HP Probook 6560b with Intel i5, 2 GB and WIN 7 - seems low spec now but OK for most of what I do. I'm finding it heavy, clunky and with all the travel I'm now doing it's just too heavy and bulky despite it sitting in a dock 80% of the time. So options are a lightweight laptop, or a tablet / convertible type device (new Thinkpad 10, Surface Pro 2/3 etc). Really just looking for how people have found having a tablet/convertible device as there main PC.
Can't move away from windows as have to use windows to demo software and connect to peripherals at the customers end on specialist programmes.
