Dell Inspiron 7390 2-in-1 Black Edition för 12.500 kronor (i vår konfiguration) kan verka väldigt lik sin föregångare, men den åtgärdar faktiskt några av de största problemen vi hade med Inspiron 7386 2-in-1. Bland dessa kan nämnas hög energiförbrukning vid tomgång, som nu nästan halverats och kort batteritid, som nu är 40% längre. Vi noterade heller inget spoltjut på vår recensionsenhet och skärmen är en aning mer ljusstark än innan. Till och med CPU-prestandan är en aning högre än tidigare trots faktum att båda maskinerna drivs av samma chip.
Vidare är UHD-skärmen tilltalande med ganska bra färgåtergivning och bra kalibrering direkt vid leverans. Den nya designen på startknappen (med sin inbyggda fingeravtrycksläsare) och tangentbordets layout fungerade båda bra i vårt tycke. Höljet har en konstruktion och design som är bra för den här klassen och som känns en aning mer robust än vissa av de tunnare metallkonkurrenterna. Till sist är Dells smarta gångjärnsdesign, som innehåller en magnetisk hålighet för Dells Active Pen, en av den smartaste lagringslösningarna vi sett för en stylus i full storlek.
Inspiron 7390 2-in-1 är på många sätt bättre än sin föregångare — som exempel har den mycket bättre batteritid och ännu bättre prestanda. Trots några små brister som rör inmatningsenheterna och det tveksamma värdet av en Core i7 CPU är den ett seriöst alternativ till konkurrenter från andra tillverkare som Lenovo och HP.
Men en del klagomål återstår. Prestandan är fortfarande en besvikelse i ljuset av resultaten från cTDP Up-konkurrenter som Lenovo’s ThinkBook 13s, som faktiskt är bättre. Portutbudet är tunt och bristen på Thunderbolt 3 och Kensington-lås kommer störa en del användare. Tangentbordet är skapligt men kunde varit bättre rörande återkoppling och den kraft som krävs för anslag. På samma sätt kräver styrplattans inbyggda knappar alldeles för mycket kraft för att aktiveras, vilket gör den ganska uttröttande att använda efter ett tag. Slutligen, även om skärmen definitivt är trevlig, hade det varit bra med ett FHD-alternativ, vilket hade bättrat på batteritiden rejält — den extra ytan kommer de flesta användare inte sakna.
Konkurrenter som är värda att överväga inkluderar ThinkPad X1 Yoga, HP Envy x360 13, ThinkPad X390 Yoga, och — på den dyrare sidan — Latitude 7400 2-in-1. Men bortsett från irritationsmomenten rörande inmatningsenheterna och jämmer över dyrare chip som inte riktigt drar sitt strå till stacken är Inspiron 7390 2-in-1 ett rimligt alternativ till de populära Yoga och x360-serierna och når mycket längre än sin föregångare.
