Installing Linux on a laptop used to be a pain in the rear. Its become much easier in recent years. I have an Acer E15 laptop. Its a low end laptop (can't afford much else,) and I run Chalet OS on it, because 4 gigs of ram won't cut it with Windows 8.1. I can upgrade the RAM but everyone knows that its a pain in the butt to unbutton a laptop (my main pc is a desktop for that reason.) It runs great, everything works, though the touchpad is a little wonky because its one of the new ones ($15 usb mouse from Amazon fixed that.) Install was flawless (I had to tweak the language settings because, but that had nothing to do with the hardware.) I used clonezilla to back up the windows install in case I need to return it.
I bought it off of Amazon after reading the reviews for it and asking questions. I won't go to worst buy, or Staples for computer equipment unless its an absolute emergency. I went there once for some memory, it was overpriced, and told them to shove off after they suggested I get a new laptop. Went to crucial and found the memory I need for less money. Read the reviews and ask questions if you decided to buy a laptop off of Amazon or NewEgg. The amounts of stars given is not a good indicator because someone will rate it 5 stars after having it for a week.
I would recommend that people purchase a cool pad for between $20 or $40. Laptops are not meant to be used non stop and they burn out faster than desktops, because you have many electronic components crammed into one place. Cool pads help mitigate that. Linux also has utilities that you can download too monitor temperature and fan speed.
