That's a bit disappointing to hear. I installed it last night, but never got a chance to exporting old stuff to import into Aperture to play with.
Given what folks seemed to be saying, seemed like it'd be a nice improvement. the UI certainly looks better, but I've always liked Aperture over Lightroom for that.
Out of curiosity, what computer are you running off of?
I don't have a decent camera so I just used my 4mpx jpegs, I guess raw may differ, not that it will be faster I assume but slower in both applications, and maybe Aperture works better compared to Lightroom then, I have no idea.
Yeah, the UI are soo clean and it's nice to have everything at ones place, I hate the library and develop tabs in Lightroom.
I ran it on 2.2GHz MBP / 2GB ram / 128MB vram.
But don't trust me, just try it, I would have prefered if I liked Aperture better since it would sound cooler to say it was only available on a mac, but well, I don't it seems =P. Both apps are good thought so I would probably do well with either.
But I still think the 256MB vram version may run it much better, and I will always hate Apple for their specs.
And the guy who got a quad Mac Pro but only the 7300 GT should probably just upgrade his graphics card, I mean, if you can afford a quad mac pro why use such a lowend card? Atleast it is fixable in the mac pro, if only they used BIOS aswell (or all PCs used EFI) so one didn't had to get a special mac version of the graphics card aswell.
