I must say I sat opposite someone on the train the other week and thought &quot;what is that noise?&quot;. It turned out to be his Surface Pro. I&#x27;m not sure whether he was doing anything particularly intensive or just checking email, but the fact that it was audible above the typical noise of a train put me off ever wanting to buy one. Imagine trying to read or watch a movie in bed with that whirring going on!
