Doesn't feel as heavy as you would think considering it's a metal frame. However I find that the battery life only applies to when it's in sleep mode -- when actively using it, it has the standard 4-6 hours of use that I experience with most other chromebooks.This was a decent (but not great) purchase considering it's a refurbished one.I have found that it lags a LOT on facebook and reddit for some strange reason. None of the other computers here act like that with those websites, and it's only those websites that lag on it.
