My eight year old son is starting to get into programming, which I'm chuffed to bits about. Unfortunately he likes to use the PC in my office and I'm increasingly working from home. I have a Macbook Air and a Samsung Ultrabook, but they're not really fit for purpose and besides - they're mine!
So I was thinking about getting him a cheap second hand laptop with a decent sized screen. The coding he's doing at the moment is all in Scratch but maybe he'll move to Unity someday so I'd like a bit of a 3D capability. He plays Lego Harry Potter on it too, which states Core Duo ATI HD 2900 or NVIDIA GeForce 8800 as recommended specs.
So... I'm thinking of eBay, used, 15" screen, appropriate CPU and GPU. No need for optical drive.
Any advice?
