Latitude 7390 2si1 arada modeli iyi bir yapım kalitesine sahip, hızlı bir sistem sunan ilgi çekici bir cihaz. Bağlantı olanakları, depolama alanı, kolay bakım imkanı gibi harika özellikleri var. Ancak işlemci performansı önceki jenerasyonlara göre sadece biraz daha iyi ve Core i7 seçeneği ne kadar doğru tartışılır. Core i5 versiyonu hem bütçe hem performans açısından daha iyi bir tercih olabilir.
Latitude 7390 2si1 arada modeli iyi düşünülmüş, sağlam ve ilgi çekici bir model. Ancak bazı dezavantajları var ve küçük bir yatırımdan fazlasını gerektiriyor. Dolayısıyla satın almadan önce yüzeyi iyice kazımak gerekli.
Bazı alanlarda soru işaretleri mevcut. Sadece yansıtmalı dokunmatik ekranlar seçilebiliyor, dolayısıyla renk kapsamı etkileyici değil. NVMe SSD, Samsung modelleri kadar iyi değil. Cihaz, boyutu için biraz ağır bunun sebebi de ekran kapağının kalın olması olarak açıklanabilir. Kapak ayrıca çok stabil değil ve durduğu yerde kolayca sallanabilir. Son olarak bir iş cihazının dönüştürülebilir bir model olması ne kadar gerekli tartışmaya açık bir soru. Dell, Latitude 7380 modeli ile aslında ortaya çok daha iyi bir çözüm koymuş ve üstelik yansıtmasız bir ekran seçeneği ile daha hafif ve daha stabil bir model sunuyor.
