Genel olarak T550 T serisinin sunduğu yüksek kaliteyi veriyor ve fiyatını haklı çıkarıyor. Hafif sayılabilecek, sağlam yapılı bir cihaz karşımızda. LTE ile sadece WiFi kullanabilen modellere göre büyük bir esnekliği söz konusu. Güvenlik paketi de oldukça tatmin edici. Klavye ve touchpad en iyisinden ve ihtiyaç duyulabilecek tüç arayüzler kullanılmış.
Performans iş alanındaki programlar için yeterli olsa bile tıkanan işlemci biraz acı tat bırakıyor. TN ekran en azından parlak ancak bu fiyat aralığı için uygun olmadığını düşünüyoruz. En öne çıkan özelliği ise şüphesizki harika batarya süresi.
