    Abstract : Popular Abstract in Swedish Minns du din första dator? Kanske köpte familjen den på avbetalning genom jobbet för 20 000 kr och kanske kan du såhär i efterhand tycka att effektförbrukningen var lite väl hög i relation till datorns prestanda. Den gick t.ex. inte att köra på batteri. READ MORE
