I don't know that you'll need it, but laptops can run hot and not hold up over time, especially if you take it with you everywhere - regardless of the weather. But Lenovo, maker of this unit, offers a four year warranty upgrade with onsite repair for a very competitive price.  Laptops in this range don't offer great warranties without paying more than this.THE GOOD-This is a good, basic laptop with-Installation is Cortana-enabled, very civilized-Most of the basic ports you need are available-Good screen quality-Lightweight-Surprisingly small power brick-Touch screenNOT SO GOOD-No wired ethernet port-keyboard is not backlit-4GB only-SSD almost half full once updates applied and Office was installed-No caseWINDOWS RELATED COMPLAINTS-S mode is a nuisance.  It's a good idea, poorly executed, because it's either/or (anything not in the Win 10 Store can't be installed) -- e.g., Chrome-Takes a long time to synch OneDrive-The i3 processor struggled a bit with Windows updates-During Win updates, the screen froze for minutes at a time (no ALT TAB between tasks, though mouse pointer was alive)-The image backup scenario is a nuisance and not Cortana-friendlyUnlink a Store device to installBecause the RAM is soldered, I don't recommend this 4GB configuration unless you are willing to limit the number of browser windows and applications you're running at a time.Probably fine for many Linux uses.
