Man behöver inte återuppfinna hjulet varje gång – det är vettigt att förbättra en beprövad produkt sakta men säkert. Dell följer den filosofin och ändrar inte Latitude E7450 helt, men har förbättrat många detaljer jämfört med föregångaren E7440.
Många förbättringar märks bara när man jämför båda enheterna sida vid sida. Chassit är nu något tunnare än tidigare och har ett något större batteri trots identisk vikt. Fläktljudet under belastning har sänkts ytterligare och både processor- och grafikprestandan har förbättrats tack vare den nya Broadwell-kretsen. Välbekanta, högkvalitativa inmatningsenheter och en mycket anständig Full HD-skärm fullbordar helhetsintrycket och motiverar det slutliga betyget på 88% - mycket bra.
Att ThinkPad T440s får två poäng mer trots den äldre hårdvaran beror främst på små saker som batteritillval och ännu lägre fläktljud. Men det visar också att bärbara datorer med Haswell är allt annat än föråldrade 2015. Efterföljaren är naturligtvis att föredra för samma pris, men många avvecklade modeller som Latitude E7440 bör vara tillgängliga för mycket attraktiva priser under de kommande veckorna.
