Kontorsanvändare kommer notera två nackdelar hos den annars väldesignade Lenovo Yoga 720-12IKB – den jämförelsevis långsamma WLAN-modulen och, viktigast, batteritiden täcker inte en hel arbetsdag på resande fot. Valet av skärm är väldigt bra bortsett från seriös bildredigering och de långsamma resultaten från SSD-prestandatesten påverkar inte den bra systemprestandan. Begränsat utbud av portar är vanligt bland kompakta omvandlingsbara, så vi kan knappast kritisera Yoga för det.
Höljets stabilitet är inte perfekt, men det är fortfarande ett lyckat chassi med en snygg design och bra konstruktionskvalitet. Active Pen, som ingår, dom hyfsade inmatningsenheterna, inklusive en tryckkänslig skärm, samt den effektiva, svala och väldigt tysta driften är andra fördelar.
Den kompakta och mångsidiga omvandlingsbara Lenovo Yoga 720 12 är billig och svarar upp mot nästan alla krav från mobila företagsanvändare. Den enda egentliga nackdelen är den begränsade uthållighet vid batteridrift.
Allt som allt så kan vi rekommendera denna testmodell.
