Hi all, I'm really torn between the Dell P2715Q and the apple thunderbolt display for my Mac Pro. I'm currently using a 27" iMac (2011) in target display mode with my Mac Pro but am going to hand that down to a family member so I need to buy a display. The thunderbolt display would essentially just be exactly the same as the iMac right, just with a smaller form factor? I'm perfectly happy with this setup but am just wondering if I should mix things up and go with the Dell 4k P2715Q. The addition of more USB 3 ports and it being slightly cheaper is nice but the lack of a built in iSight is a shame. Does anyone have any thoughts? EDIT: I should have said, I do scientific work, so predominantly text editing, but also some photo work (on the side), no gaming.
