In review: Lenovo ThinkPad E450 20DDS01E00. Test model provided by CampusPoint.

%80lik değerlemesi ile Lenovo, ThinkPad E450 modelinde birçok şeyi doğru yapmış gibi. 15 Watt sistem çipi ile kullanılan SSD uzun batarya sürelerini ve idareli/sessiz kullanımı mümkün kılıyor. Full HD ekran, kullanış yönünden büyük kolaylık sunuyor. Pahalı T serilerinden alınan bağlantı özellikeri ise tek kelimeyle harika.

Lenovo, hedef kitlesi olarak üniversite öğrencilerini seçmiş. Bunu hem saydığımız özelliklerden hem de ek olarak oyun da oynanabilecek bir kart olan Radeon grafik kartının kullanılmasından anlıyoruz.

Elbette karşımızda mükemmel 14 inçlik cihaz yok. Düşük TFT parlaklığı, özellikle batarya kullanımında, can sıkıcı türden. Bakım olanakları çok zayıf. Ancak bunlar sizin için bir sorun teşkil etmeyecekse, makul bir fiyata bu modele sahip olabilirsiniz.
