I sat down on the train, two laptops, a tablet, and an e-reader crammed in my purse. There was a moment of relief -- I'd managed to snag a seat on a rush hour train -- and then, I felt a moment of sheer terror. My purse felt unusually light despite being full of gadgets. Certainly too light for a purse containing a 38cm laptop. Those are giant unwieldy monsters that never let you forget they have been packed away in your bags. But when I yanked my purse open and peered inside the relief returned. The newest 38cm Samsung Notebook 9 was tucked away safely, so light I forgot I had it.
