Kontra
Az új Dell Latitude 7390 majdnem mindenben kitűnően teljesít. A nem túl durva 1400 eurós (~$1732) árú modellel egy kerek egészet kapunk, amelynek alig van hiányossága.
Itt a kicsit kicsi, de amúgy jól sikerült billentyűzetet, a középszerű touchpad gombokat, a Thunderbolt 3 hiányát és a zajos Space gombot kell megemlítenünk. Ennél is kisebb design hiba, hogy a fedél felemeli az alapot, ha olyan 135°-nál nagyobb szögben nyitjuk ki. Amit tényleg nem szerettünk, az a rémes hangrendszer és a gyenge ujjlenyomat olvasó volt.
Nem csak sokkal több elemből áll a "Pro" lista, de fontosabb dolgok is vannak rajta. Még az i5-8350U is egy kicsit túl sok a Latitude-ben irodai feladatokra, de mivel az üzemidő így is remek, egy kis plusz erő soha nem árthat. Az egyszerű, de kiváló minőségű ház, nagyon jó beviteli eszközök, a biztonsági funkciók, átgondolt csatlakozókínálat, kontrasztos kijelző, a Windows 10 Pro és végül de nem utolsósorban a 3 éves jótállás, valamint a csendes működés egyértelműen megérdemlik az ajánlásunkat.
