Ok, for those who are tired of hearing about Macs, you might not want to continue.
Although these are some thoughts stimulated by MacWorld, it's an interesting observation I heard on a Podcast. It seems like this year there's not really a single 'gee whiz' product (although the MacBook Air and Apple TV updates are wicked sweet), but more an evolutionary set of updates and upgrades.
Personally the most exciting announcement was the Apple TV, but looking closer at the fine print there's some things that were not touted in the Keynote that I think are worth mentioning.
The first one is the fact that you no longer have to choose a 'Source' when viewing your content on the Apple TV. Although you can pick a single computer that content will sync back and forth to, all your other iTunes libraries and photos will be available directly on the Apple TV without having to find which computer it's on. This addresses one of the most common complaints I've heard about the Apple TV, of having to switch around the different computers to view all your content. Now it's just 'all there'.
Another thing that didn't seem to get mentioned, and I haven't found more details on is that apparently the HD content is not available on iTunes directly, only on the Apple TV. I've heard this and read this on the various blog posts, but haven't found something confirming this from Apple. It may just be that because rentals are now available on iTunes, and not the HD versions assumptions are being made. I think it's more likely that the HD content is going to be rolled out with the updates for the Apple TV.
The remote drive for the Air is also exciting, from what I understand this will not be something that's limited to only being available for the Air, but can be used by all Leopard Macs, or actually any computer that has the remote drive software installed.
The Time Capsule is VERY exciting, and I'm really hoping that there will be an update for existing Airport Extreme's to enable them to be used the same way with there external drives.
It seems like it's going to be another great year, and I'm really looking forward to what's coming with Leopard as it get's enhanced and tweaked. I already love it tons more than Tiger, and it's only been out for a few months.
