Återigen har vi blivit ordentligt imponerade av en maskin från Dells Latitude 7000-serie. Tillsammans med Lenovos ThinkPad-modeller och HP:s EliteBook-modeller står Latitude-modellerna långt över resten av konkurrensen i företagskategorin. Dom har en genomtänkt design, är smart uppdaterade och har setts över noggrant. Även om 7490 på alla sätt främst är en iterativ uppdatering till 7480 så lämnar den väldigt lite att önska. Höljet är robust, nedtonat och attraktivt, vikten är hanterbar, inmatningsenheterna är i toppklass, prestandan är riktigt bra, batteriet håller länge och den är en tyst kollega. Dom få områden där vi önskar en förbättring rör skärmalternativ som matchar konkurrenterna, förbättrad värmehantering och bättre högtalare.
Återigen har vi blivit ordentligt imponerade av en maskin från Dells Latitude 7000-serie. Dagens Latitude 7490 för 17.000 kronor förtjänar att övervägas av alla som letar efter en högkvalitativ företagslaptop.
Dagens billigare konfiguration saknar Core i7, NVMe-lagring, tryckkänslig skärm och en del av dom biometriska och säkerhetsmässiga funktioner som recensionsenheten från April hade - men den kostar också bara 17.000 kronor (jämfört med över 20.000 kronor för den tidigare modellen). Behöver man inte dualkanalsminne eller någon av dom tidigare nämnda sakerna så finns det väldigt lite att klaga på hos det här upplägget. CPU-prestandan ligger runt 10 och 15 procent under den i7-utrustade enheten och GPU-prestandan är runt 15 - 22 procent lägre (även om detta också beror på dualkanals-minnet vår i7-konfiguration hade). Således rekommenderar vi bara att uppgradera till en sådan SKU om CPU- och GPU-prestanda i toppklass är av yttersta vikt. Bredvid X1 Carbon, T480s, EliteBook 840 G5, och Latitude 7390, förtjänar 7490 definitivt att övervägas av alla som letar efter en högkvalitativ företagslaptop.
