If you are sure you are not going to be using music, video or gaming software, then go for a laptop with a fast Intel I3 processor (You are wasting money with an I5 or I7 for your use) 4GB of Ram & a 250GB SSD (Solid State Drive), I would also recommend you go for at least a 15” screen.
If you need extra storage at a later date, you can pick up a USB 3 portable drive for minimal cost. (This also has the advantage that all valuable information can be stored away from the laptop as well as being able to be used with other computers) Also remember that if you have broadband (With an unlimited Data Plan) you can use cloud storage for extra space.
Finally try out the keyboard and screen to make sure you are comfortable with them. (This is a vitally important point that most people miss)
Hope this helps
