Upgrade the pillar . Upgrading the floor doesn ' t really do anything except improve it ' s durability <| sep |> It ' s probably allowed , I wouldn ' t recommend it though . Having a laptop gives you a huge amount of extra flexibility . It ' s certainly still possible to get by with just a desktop but as someone who wanted to stay on a desktop , I think it was definitely the right decision to get a laptop in the end . Another consideration is that certainly for Cambridge I ' m not sure about Durham , you will be kicked out of college over the vacations . Particularly if you live far away from Cambridge , you should consider whether it ' s realistic to drag your entire setup between university and home six times a year .
