Is this the LTE model?
Despite my recent rant against this exact processor, the kuntz of this computer is weight and battery life, not power (and it is plenty for office work). You should get more than ten hours even if you are downloading (and 15 hours of word processing).
2 haaros: This is not the Galaxy Book Pro, just the regular one. Primary difference is the weight - the Pro is about .8 lbs lighter - and the battery life - the vanilla gets 10 hours and the pro gets 17 hours. Also, you cannot upgrade the RAM.
Agav, the computers are not worth $1157. They are worth about $900 IMHO. Which makes $790 a good price for non-warranty computers.
Review (i5 version, but the 11th gen i5 and i7 are virtually identical)
