Tekeri her seferinde yeniden icat etmeye gerek yok. Kendini kanıtlamış bir ürünü adım adım geliştirmek mantıklı bir adım. Dell bu felsefeyi değiştirmiyor ve Latitude E7450 ile de aynı yavaş adımları takip edip mükemmelliyeti kovalıyor.
Birçok optimizasyon sadece iki cihazı yanyana koyduğunuzda anlaşılabiliyor. Kasa eskisine göre biraz daha ince ve benzer ağırlığa rağmen daha iyi bataryaya sahip. Ses üretimi daha da azaltılmış ve grafik performansı arttırılmış. Arayüzler yüksek kaliteli ve çok makul bir Full HD ekran genel izlenimimizi belirliyor.
