As per the other thread:
<blockquote.
Get a windows laptop (i.e. anything that isnt a chromebook) and a student licence for Word, excel etc (which is significantly cheaper than the grownup licence).
Yes google docs is free, so is open office. But you will then waste days of your life transposing formulas from google sheets to excel as they have different functions and vba wont work . Or writing your dissertation in open office only to find 2 hours before the deadline that the formatting is all wrong when you try and print via word on a university computer.
In terms of spec your buying the ford fiesta of laptops, the best you can do is a fiesta and the worst is a corsa and in reality both will do what you need and are basicly the same. Except a chromebook, thats like asking what bike to get and ending up with a Segway.
Think the other thread had some good recommendations for refurbished business laptops.
