Lenovos Tab 4 8 är en prisvärd surfplatta som misslyckas med att stå ut. Dess design är ganska återhållsam och konservativ, skalet är mottagligt för vridning och tryck och kameraupplösning, bildkvalitet, prestanda och anslutbarhet är typiska för dess klass.
Med andra ord: Lenovos surfplatta är inte speciell på något vis men är samtidigt pålitlig på många sätt. Den ljusstarka skärmens betraktningsvinkel är superb, dess GPS är exakt och enheten blir inte särskilt varm under belastning. Dom framåtriktade högtalarna, dess rena version av Android och dess stor batteri (som Lenovo dock inte lyckats krama någon extra batteritid ur) är särskilt noterbara. Den kan göras barnsäker med valfria tillbehör och vi vill återigen betona faktumet att tvärt emot många andra tillverkade så har Lenovo faktiskt spenderat tid, pengar och energi på att fundera över hur man kan förbättra en billig surfplatta med tillbehör.
Lenovo Tab 4 8 är en pålitlig 8-tums surfplatta utan några särskilda finesser men som har en solid prestanda i övrigt.
Allt som allt, surfplattor som Lenovos Yoga-serie är mycket mer innovativa än Tab 4 8. Men den senare erbjuder pålitlig prestanda utan några egentliga brister för ett hyfsat pris.
