I firmly disencourage people to purchase Aperture these days.
To everyone asking me for advise as a Pro photographer.
Apple attitude on this issue is of abandonement and ignorance of users needs.
Unfortunately, the feeling is that this is going to be the permanent standard.
They are not providing translations, not providing support to models such as X-Pro1 that has received inmediate reaction from major developers, neither do care for users that openly claim for RAW support for an extended model as X-10.
This is somehow another sign of apple arrogance in term of market predominant coompany.
If Apple do not begin to lose sales and an importan market share this is going to be worse and worse.
Best way: Ignore Aperture.
Adobe is nowadays the ONLY option for photographers.
I don't like Lightroom so I must select my shots with Photo Mechanic, or Xnview and then go to photoshop.
Sick of Apple.
