I'm a little underwhelmed at the Leopard sneek Preview. All they have shown us is a couple of new Apps (Time Machine, Spaces, ...) some App updates (Mail etc etc).
Not really seen any major OS changes yet (Finder ...)
I think they have still a lot of work to do in the next 7-8 months.
One thing I think is missing from the little we have seen so far Is an good "Out of Office" that integrates Mail and iCal (and OSX Server if you have it). I'm using a Squirrel Mail plug-in at the moment, but it does not have that "Apple" simplicity.
If Apple want the Mac to be adopted in the work environment they need to get this sorted. ie: Just put your vacation dates in iCal, click an "Out of Office reply" button, enter your reply text. Done! When you vacation passes the reply stops. It cant be that hard for them to do this, can it? Maybe it will be part of the new iCal Server on Leopard server???
Oh. another thing NEEDED is "Address book sharing" without .mac. An Address book server that automatically updates all the local LAN Mac's address book's and updates itself from the same local LAN Mac's ie: you have a list of clients in the address book on all your LAN Mac's. Client "A" changes his address, One person updates their Address book and POW! everyone's address book is updated.
These ideas would really work in the day to day running of a company. Fancy Templates in Mail that you can drop pictures into frames are pretty cool, but they are not going to make my life any easier.
Just my 2p worth
