Med ThinkPad Helix 2 har Lenovo förbättrat konceptet med att kombinera surfplatta och kontorsdator i en och samma enhet. Det har krävt en del hårdvarukompromisser, men totalt sett är den mycket bättre tack vare den nya CPU-plattformen.
Strömsnåla Core M-5Y71 imponerar inte bara med sina låga kylningsbehov (den passiva kylningen räcker), utan också bra prestanda som är mer än tillräcklig för alla kontorsprogram. Den förbättrade energieffektivitet har också en positiv effekt på batteritiden – det integrerade 35 Wh-batteriet klarar lätt 6 timmar eller mer. Med tangentbordet Ultrabook Pro (tillval) blir enheten ännu mer uthållig, men också betydligt dyrare.
Det här är också vår främsta kritik: det höga priset. Vår testenhet kostar för närvarande nästan 1400 euro, vilket är för mycket trots komponenterna (8 GB RAM, 256 GB SSD, LTE). Priset är ännu svårare att acceptera i en enhet vars byggkvalitet och chassi inte helt uppfyller Lenovos anspråk på ”premiumstatus".
Slutligen tar vi en titt på utmanarna: potentiella Helix 2-köpare bör överväga alternativ som Dell Venue Pro 11 eller Microsoft Surface Pro 3. Dells enhet har ett tilltalande pris/prestanda-förhållande beroende på konfiguration, medan Surface, med sitt mycket sofistikerade chassi, också är ett starkt alternativ till Helix.
