Running photoshop, browser with many tabs open, Spotify, Dropbox, various peripherals, etc., doesn't seem to slow down. Very happy. No problem with set-up/Windows. I kind of wish they wouldn't send the wired mouse and keyboard along with it, or at least give you a choice, so it doesn't go straight to the landfill. Will order again.Update: HD died today, 4/21/20 RIP you were a great machine. Lasted a year.  Getting another.
