İtiraf etmek gerekirse ödediğinizin karşılığını alıyorsunuz. ThinkPad T450 kesinlikle "ucuz" etiketine sahip bir model değil. Ama T450s modelleri ile kıyaslandığında biraz öyle görünüyor, elbette kıyasladığımız modelin çok üst bir sınıf olduğunu belirtmek gerek.

Oldukça hayal kırıklığı yaratan TN ekran dışında T450 neredeyse eleştiriye hiç yer bırakmıyor. Kasası, bağlantı olanakları, arayüzleri daha pahalı kardeşinden çok farklı değil. Ses ve sıcaklık üretimi de oldukça düşük. 

Kısacası ThinkPad T450 modeli genellikle evde çalışan ve harici monitörü olan kullanıcıların ilgsini çekebilir.
