Saw it online and noticed that all laptops are Thinkpads. Did a little research and found out that they've been using Thinkpads since 1993...
"The ThinkPad 750 flew aboard the Space Shuttle Endeavour during a mission to repair the Hubble Space Telescope on December 2, 1993. The ThinkPad 750C's task was to run a NASA test program which determined if radiation inherent in the space environment causes memory anomalies in the 750C or generates other unexpected problems.[28]
Throughout 2006, a ThinkPad A31p was being used in the Service Module Central Post of the International Space Station and seven ThinkPad A31p laptops were in service in orbit aboard the International Space Station.[29] As of 2010, the Space Station was equipped with 68 ThinkPad A31 computers along with 32 new Lenovo ThinkPad T61p laptops plus a dedicated IP phone which also has limited video phone capabilities.[30] Work incorporating those laptops into the station's LAN continued into June 2011.[31] All laptops aboard the ISS are connected to the station's LAN via Wi-Fi and are connected to the ground at 3 Mbit/s up and 10 Mbit/s down, comparable to home DSL connection speeds."
