Dell Lalitude E6440 hakkında çok iyi şeyler söyleyebiliriz: giriş arayüzleri, sağlam metal kasa, iyi bağlantı olanakları, yüksek sistem performansı, makul hoparlörler ve rahat bakım imkanı. Tüm bunlar güvenlik özellikleri ve garanti opsiyonları ile birleştirilince ortaya iyi bir laptop çıkıyor.
Tek sıkıntı kesinlikle ekran. Ekranın kalitesi bu fiyat aralığı için kabul edilemez. Yüksek siyah değeri, ekrandaki mavi çizgi, eşit olmayan aydınlatma ve düşük renk keskinliği ile limitli ekran açıları. Bunun sebebi ne? Öyle sanıyoruzki Dell kullanıcılarına bir iş laptopunda en önemsiz nedir diye sorup bu cevaba ulaşmış. Harici bir monitör ile bu sorunlar elbette aşılabilir.
Diğer küçük dezavantajı da solaklar için fan çıkışının konumlandırılması. Ancak tüm eleştirimiz bu kadar. Dell, Latitude E6440 modeli ile iyi bir iş çıkarmış.
