Acer Aspire 3 laptop. This is my laptop I used to use for data engineering across British Motorsport (including BTCC). it's more than enough to look at the data and do office based tasks. Battery lasts well, and does all it needs to, I have just upgraded to a laptop capable of 3D modeling now too. Any questions, please ask. As a guide this laptop sells for £120 at CEX, so price reflects that.
