Macworld 2004 Keynote Updates
If I can't get in or online, you'll know it because the above page won't ever change :).
Update: Well, I was there, but there wasn't any wireless connectivity available (except to Steve!), so no updates. My take on the day's news, after having heard it and toured the floor? The G5 XServes are very slick boxes (though still no dual power supplies, from what I can see); Final Cut Express 2 looks like a solid update; and the iLife updates are all appreciated, especially the speed in iPhoto.
Regarding the iPod mini, here's my take on it after spending a few minutes with one. I much prefer the mini's "buttons on scroll wheel" setup -- the "soft" buttons on the main iPod are just too sensitive to the touch; the mini's buttons require a definite click to activate. The brushed aluminum is really nice, and the size is nice draw. However, I think Apple missed the pricing sweet spot by $75 to $100 or so -- using Steve's own "only $50 more" example from the keynote, for only $50 more, you can get a real iPod, and it's now 15gb instead of 10gb -- so that's 4x the storage for $50. At $149, they probably would have sold as many as they could make; at $249, I think they may find them sitting on shelves ... only time will tell, of course.
I asked someone in the Apple booth about iPhoto and free vs. pay availability. Here's what I was told, at least as of today: The new iPhoto will only be available as part of the iLife '04 package; it will not be downloadable. This matches the treatment that Apple gives iMovie and iDVD -- they're both bundled with new Macs, or they're available as part of iLife. So as of today, it appears the only remaining free iApp is iTunes, and I expect (since it sells iPods) that it will remain free for the forseeable future. From my seat, the speed gains and "on the fly" handling of rotation, rating, and deletion of new photos make it worth the $49 all by itself; the other new features in iDVD and iMovie are just icing on the cake.
