Arrived at 3:30PM. Was in such a tiny box - I was expecting the same size of box as Tiger.
Popped the disc in, restarted and did an Archive and Install. After just over an hour, I was ready to boot up in Leopard for the first time. It had retained all my settings, dock icons, size, aswell as all my bookmarks etc.
So far, all Applications have run without needing reinstalling - and I was amazed to see games like Football Manager 2008 ran without needing reinstalled or a patch to work on Leopard. Fantastic stuff!
The new Finder is awesome too - I love using Cover Flow and Quick Look.
However, I've found it not to be as snappy as I was hoping - Core Animation seems to struggle on my Santa Rosa MBP. Applications like iPhoto load a lot quicker than Tiger, but still not almost instantly. I wish they would give you the option to specify a default Finder window size and lock it to that. I hate having to resize my Finder windows so they are all the same size etc..!
With Cover Flow also - there is a sense of sluggishness. Such as when you open a folder for the first time and it is generating the thumbnails, the scrolling is sluggish. And it takes a while to generate the thumbnails.
Bit disappointing, but can't expect it to work right away I guess. Quick View has a same issue, there is a significant delay between pressing space bar and the preview (if it is something like a movie) loading. Word documents get previewed instantly.
Also, I have extreme troubles accessing my Air Disk - it is no longer found on the desktop but on the Side Bar under your router name. It works, and then doesn't. I can open my router's server (if you look on the screenshots, mine is called Reason). It tries to connect, I don't get a dialog saying it can't but it never connects. So I can't access my data. Anyone else with that problem?
That was the small negatives I had - overall I love it! The Finder is so sexy and slick, and it looks and feels so nice. I urge you all to upgrade!
