I have had HP laptops for many years, both for work and for home. I bought this HP ZBook mainly to do photo editing. As usual, the build quality and ergonomics are excellent. The screen quality, resolution and colour rendition are very good too. The laptop comes with HP Wolf Security does not appear to be as user-friendly as more domestically available AV software.
The only negative point for my laptop (and previous HP laptops) is that the estimated battery life is in practice less than what was quoted on the online details for this laptop - this is with just using the laptop for browsing / emails with the recommended battery settings. That aside, I still feel 5 stars is a true rating for my purchase.
