Nya Yoga Book har en E-Ink skärm som gör den väldigt unik. Den största fördelen är dess mångsidighet. Den är extremt liten och lätt och kan användas för att rita på, som en laptop, en surfplatta eller en e-läsare. Men flexibilititen resulterar också i en del kompromisser.
Som exempel är tangentbordet inte lämpat för den som skriver mycket och det är heller inte bakgrundsbelyst. Det magra portutbudet kan vara problematiskt för traditionella laptop-användare. Om det bara är en e-läsare du behöver kan du troligen hitta ännu lättare enheter.
Lenovo Book riktar sig åt personer som vill kombinera alla dess funktioner (tryckkänslighet, penna, e-läsare, osv) i en och samma enhet. Den som letar efter en normal laptop blir nog mer nöjd med en annan enhet.
Oavsett är det förvånande att se hur bra Lenovo har lyckats med att kombinera alla dessa funktioner i en såpass lätt enhet. Designen och de häftiga funktionerna (knackning) gör Book C930 riktigt iögonfallande. Eftersom vi inte har en separat kategori för E-Ink skärmar i vårt utvärderingssystem har vi lagt till två poäng till resultatet manuellt.
En del kan tänkas tycka att priset är en ytterligare nackdel. Med ett utgångspris på 10.500 kronor kostar enheten ungefär dubbelt så mycket som föregångaren gjorde. Utöver de många förbättringarna har en del funktioner också försvunnit. Möjligheten att digitalisera bilder från papper finns inte längre. Den bättre huvudkameran som fanns på den tidigare modellen saknas också och tyvärr är batteritiden betydligt kortare jämfört med föregångaren. Istället har prestandan ökat dramatiskt och dessutom är skärmen bättre. Sist men inte minst: enheten har för tillfället inga riktiga konkurrenter.
