Like another recent reviewer, I removed Windows (I rarely use it) and loaded Linux.Arch Linux, i3 window manager, Chromium browser, MPlayer, some NodeJS apps and moreAfter the initial disk format/partition, I had 29G of space to install everything. Currently with all the programs and features I want there is still 21G left!I only had a slight issue installing using EFI as bootloader, but after that was resolved everything else just worked!Battery: I had this unit on for 5 hours - most of that streaming videos. After 5 hours I still had 33% battery life left.I am surprised how much I enjoy using this little laptop. Note that the most current specs (Aug 2019) for this does have a USB 3.1 and a USB 2.0. You can look this model up on HP's website for all the specs (11-ah117wm)
