We have two key machines in my household – my PowerMac G5 and Carolyn’s MacBook.  Last weekend, we upgraded to Mac OS X Leopard, and so far, so good.

I haven’t put Time Machine through it’s paces yet – I’m waiting for the update that will enable network-attached storage.

So far, the biggest delta has been the built-in applications.  The new iChat has miraculously cured whatever packet authentication issue had cropped up that prevented me from accepting video chats.  Mail is substantially improved, and although I’m not using it’s new RSS reader, I do like the new interface refinements.  I’m noticing that it’s a bit slow rendering HTML email compared to 10.4, however.  For all the uproar, the new dock is just fine by me, although I find the little glowing balls don’t say “active” to me the way that the old arrows did.

To some extent, I can feel that this is the first OS where the PPC support is no longer primary.  Carolyn’s MacBook feels snappier after the update, my G5 feels a bit slower.

It’s always amazing to me how hard it is, before the upgrade, to provide a rational reason for the upgrade.  Then, once you do it, it’s amazing how quickly all the machines with the older systems feel… dated.

I’ve been on Leopard almost a week, and now my MacBook Pro at work with Tiger on it feels… old.

Thank goodness IT has given it’s blessing to Leopard installs around the office.  🙂
