not sure where to ask

between acer iconia 8 w and lenovo miix 2 8, which will be much worth and (maybe) futureproof (win10?)

need: portable tablet for productivity (word/excel/powerpoint) thesis/report for phd, good battery life. windows only. no android (already have nexus 7 2012)

price wise: iconia rm499 vs lenovo miix 2 8 rm999

already have aspire s7 and mba 13 for proper laptop.
