In reply to Alan Breck:
> Any actual users of laptops for photo editing out there??
What exactly are you hoping for here, there isn't one better laptop for editing photos than another, it's not a specialised task, apart from the few things that have been pointed out to you you would struggle to buy a dud from Dell, HP, Lenovo etc
If you were asking for a laptop to run Autocad, SCADA or other specialised stuff then the answer would be different.
Just go into PC world, look at the £500 laptops, choose one you like with as much and buy one, load Lightroom and edit away, simples.....
