The latest Aperture (1.5.1 as I type) supports any old graphics card, and therefore runs on my Mini. Loads of folk out there reckon it's too slow to be usable, but the brief play I've had with it reveals that it's more or less the same, speed-wise, as the latest Lightroom beta (4.1).

At times, there is a spinning beachball, but it isn't there for long.

I would miss the workflow sections of Lightroom if I had to use Aperture.

But I like the way Aperture creates a new image for each adjustment you make to the original, so you can have 'versions' without having to export multiple times.

And the way it uses 'stacks'.

So the jury's out on which of these I'll eventually buy once Lightroom's released.
