iPhoto finally made 1.0 (with version4)!!
On a... 533 Digital Audio G4, 64MB GeForce4MX, 768MB... I dumped 5000 4MP pictures (canon S400 source) into it.
Scrolling entire library was smooth and responsive, resizing entire album thumbnails was fast and responsive. SHOCKING!
I wish the program wouldn't quit when I close the main window though.
Rendezvous picture sharing is way cool and isn't all that slow, even over my 802.11b network at home.
Overall this feels like a very solid 1.0 release... seems like iPhoto has been in beta forever!
