I use a windows 8.1 laptop plugged into a 27 inch Hp envy monitor using HDMI, and wireless printing. When I need to travel I just take the laptop and use a google nexus 7 for mobile checking or hanging out (eg. Using IB mobile app to check on the markets etc). Chrome syncs to all my devices which is great and I use multiple hard and soft copy backups of all files (USB, HD, Cloud - Skydrive, Symantec). I also email myself some encrypted files to store them with my email provider. If it all burns down I have copies in and out of the office and house in soft and hard format. USB on keyring is a good idea as your keys tend to go where everything else is not!
