Inmatningsenheterna var imponerande – tangentbordet kännetecknas av ett jämnt och väl tilltaget djup. Vi konstaterade samma sak med pekplattan, där enkla- och multi-touch-gester fungerar smidigt. Även om vårt testexemplar kan placeras i mellanklasskategorin för företagsdatorer, är en IPS-skärm installerad som presterar bra vad gäller kontrast och ljusstyrka.
När det gäller systemets prestanda visade sig Delldatorn vara en stark utmanare i kategorin. Latitudemaskinen var också relativt tyst och sval. Men liksom Lenovo ThinkPad T440s kunde temperaturkurvan varit något bättre.
Tyvärr är inte batteritiden tillräcklig för en hel arbetsdag. Även om Dell inte erbjuder något större batteri finns en extern lösning som inte är direkt billig. Latitude E5450 kan rekommenderas för företagsanvändare, men det finns många utmanare i prisklassen.
