So far, I really like the SP4! I have been using PCs and Macs side by side for many years, and so far all my mobile devices have been from the Apple ecosystem. I think this is likely a driver issue and am not worried about it. The only thing I notice are some unusual flashes of tint/discoloration when scrolling some webpages. The new unit doesn't do this, and the camera works as expected. The first (apparently defective) unit also locked up frequently. However, since they were unable to resolve the issue, they were great about just swapping out the unit for a new one. The manager did suggest that this could be a software issue from time to time he reported that they see different behavior from units of the same model, even with all software updates applied.

The staff was unable to reproduce the issue with their SP4 units on display, and my SP4 was replaced with a new unit from their stock. I made an appointment at the Bethesda Microsoft store yesterday, where the rear camera issue I described above was immediately identified as a technical issue and not user error.
