Ortalamanın üzeri arayüzler etkileyici. Klavye gayet kullanışlı. Her ne kadar cihaz orta segmentte yer alsa da, IPS ekranın kullanımı kontrast ve parlaklık yönünden iyi sonuçlar alınmasını sağlıyor.
Performans yönünden rakipleri kadar iyi. Malesef batarya ömrü tüm iş günü için yeterli değil. Daha büyük bir batarya opsiyonu olmasa bile harici çözümlerle bu sorun aşılabiliyor. Günlük iş rutininiz için önerebileceğimiz bir model.
