Iron

Hello!
I need a laptop, and preferably an ultrabook.
Requirements:
1. Linux will be installed on it, most likely Gent or Arch, there are no special wishes for the video
2. The laptop will be used for development, i.e. it will have vim, a browser, and Ruby
3 on it. It should be as thin as a tablet, about 13-14 inches diagonally.
4. The case should not play, and the keyboard should be as comfortable as possible, preferably with a rubberized coating, or simply waterproof. Lighting required.
5. The charge should hold at least 7-8 hours, why is it an ultrabook, I need a controller that will turn off the battery and work from the mains when connected.
6. Hard drive - ssd (the drive itself should not be rare, so that if you change it yourself)
7. It would be very good. it would be cool if there were no Namlok keyboard and a keyboard with arrows and buttons (delete, Print Scr, etc.). In general, only from capslock to enter.
