I have an older version of this laptop. Quite old now, actually, and still going strong. It's excellent, and I'll be getting another one when the time comes, for sure.
4K is poppycock to me, personally. Pixels are my profession, so I like being able to see them. It's hard to work on something that's too small to see. However, that's just me, I realise it's not a broadly-held view.
