I was a little disappointed to read this review. Admittedly, the reviewer brought up some interesting points. But at the same time, they completely failed to recognise that Aperture is fundamentally different to Photoshop and was never intended to be a replacement for an image editing program. I certainly would not expect to see anyone using just Aperture and not Photoshop.
The program is intended as a smart way of managing RAW files, with all of the camera meta-data and so on, and it achieves this task pretty well. It automatically stacks items that were taken in meter-bracketing mode or burst mode. It can adjust white-balance points and so on easily. It would not surprise me to see professional photographers using Aperture to import and manage their photos, Photoshop to perform higher level tasks, and Adobe RAW export for conversions.
RAW conversion has always been a sore spot for photographers; there are many options and all of them give different results, and while some people will swear by Bibble and say they hate Adobe RAW conversions, others will say the exact opposite. So this reviewer preferred the Adobe convertor to Apple's; fair enough then.
As a first release, I think Apple have done well. It isn't for most of us - only the sort of photographers who have to deal with hundreds or thousands of shots each day would be likely to benefit from it. But for this demographic, it is a very useful tool.
