A couple of things that have not been covered so far:
one clarification: the drawers open on the last side in which they opened if there is room for the drawer. so close the drawer, move the app all the way to the right. You can then move the apps whereever you like as long as there is room for the drawer.
I should also mention that you should be able to customie the toolbar to move the icon to open the drawer to the left side of the toolbar (maybe with a separator).
also for the record, I muuuuch prefer the drawers to the right. They bug me in the left. I want to go to the top left to read stuff (that is where people start reading afterall), not to use tools.
about mail - I like mail a lot more than any other tool that I used. I love the search bar, and the spamcop .bundle is phenomenal. Mostly, however, I like having the quantity of new emails shown in the dock. I like to eb able to compose a new mail message by clicking on an item in the apps menu and I also love the mail bouncing and redirection features.
also, when you drag messages to the side of a mail window, if you drag the messages to the left, the drawer will open on the left (if there is enough room).
I can't really say much about the addressbook. I never used it until I iSynced all my palm contacts (and ditched Palm Desktop), but the idea of hacing a central contacts database is absolutely great. I downloaded iAddressX. This app uses the addressbook database to put all your contacts on a pulldown menu. for each type of entry, you can display in large type (to go to the phone to dial a phone numer), copy (to paste into documents) or paste at the current insertion point. for email addresses, you can also create a new email with the selectd email address.
as I said, I can't say much about addressbook (since I usually edit things on the palm anyway), but the central contact database is an incredible feature. I expect to see more great apps and more disparate apps sharing this central resource)
(for completeness) - Help is really in need of help! (could not help myself) but I think it largely needs performance tweaks.
I think you totally missed the point about iCal (performance *does* suck, but (like addressbook) you can sync it with your palm/cell phone/iPod (I don't have the cell, but this syncing makes the iPod a viable weekend PDA (palm during the week).
one more thing, the power of iCal is not getting your neighbors calendar (although that is ok I guess). the power of iCal can be seen here:
http://www.icalshare.com That web site has over 500 calendars you can subscribe to! It has calendars for everything from Mac Events to Sports events for many sport types and teams to conert dates, movie release dates (theater and DVD/Video) and holidays (both religious and country-specific - over 60 holiday calendars!).
one warning: don't subscribe to too many calendars as this can make the performance worse. I certain the performance will be squared away. I mostly use iCal as a way of getting those calendars into my palm and iPod! You should not underestimate how useful that truly is!
one more thing: Apple's iCal is standard's base. iCal is not available on Lunix or Windows, but there is a Mozilla Calendar project in the works that uses the same, open standard format. You can subscribe to iCal calendars with this software and publish calendars to which iCal users can subscribe:
http://www.mozilla.org/projects/calendar/
You also forgot iSync (which is *incredibly* slow right now as it does not do incremental changes to devices. iSync *is* slow, but this is easily overcome by the fact that my calendar/contatcs are now synced between my computer, palm and iPod. Not only that, but several internet calendars I subscribe to are also synced to these devices!
