By default, the iPhone SDK package available free from Apple’s site will run on a PowerPC-based Mac but omit the iPhone SDK-related files, installing only Xcode 3.1 beta and a series of other files. This routine is easily circumvented via the shareware tool Pacifist, which can be used to force an installation of the entire SDK package on PowerPC-based Macs.

Follow these steps:

• Drag the iPhone SDK package onto the Pacifist icon
• Select the top entry, “Contents of iPhone SDK”
• Click the “Install” button in the upper-left corner and enter your administrator credentials

Google Map Addresses

View a detailed map of any address in Address Book. Just hold down the Control key while clicking any address and select “Map of” and Safari will show you its location in Google Maps.

Everything I own should give me one click access to a map; ala iPhone.

UI Recording and Playback

Add even more capabilities to your workflows. Use a new action called Watch Me Do that lets you record a user action (like pressing a button or controlling an application without built-in Automator support) and replay as an action in a workflow.

Imagine an OS that packages in macros. I can finally level up my fishing skill in WoW.

Dashcode IDE

Quickly design, code, and deploy your Dashboard widget. Dashcode is a completely integrated development environment.

A visual IDE built specifically so I can create little widgets that make my life easier; yes, please.

Automatic Packaging and Deployment

Deploy your widget in one click. Dashcode organizes all the files that make up your widget, including images, stylesheets, and JavaScript. Adding new files is handled automatically by the project manager.

Automagic packaging and deployment so I don’t have to spend 4 days figuring out I forgot to make a __config.xml file.

Wikipedia in Dictionary

Harness the power of Wikipedia when you’re connected to the Internet — built right into it’s Dictionary. You get a great Mac OS X user interface with super-fast searching and beautifully laid out-results.

Easy access to information from Wikipedia. I wonder if they could have optionally stored a copy on disk and update periodically so it didn’t require an internet connection. I can’t wait until they forget to renew the domain and a search for book reports on Abe Lincoln(NSFW) returns TMI.

Multiple Logins

In Leopard, iChat allows you to log in to all your chat accounts simultaneously, whether you use .Mac, AOL, Google Talk, or Jabber.

Later Trillian, I didn’t want to pay for you anyways.

Persistent Chat Windows

Pick up right where you left off by choosing to have iChat remember open chat windows and their contents even if you quit and restart.

I’m obsessive about keeping open chat windows and I am easily annoyed by people that close them after each response and forget what the hell we were talking about. I have them on a group list called ‘assclowns’.

More Smileys

Have fun with the cool new collection of smileys built into iChat.

Fuck.

Watch for My Name…

Receive an alert when someone calls your name in a group chat. And never miss a comment directed to you.

I always need this in IRC, and for some reason I can’t figure out how to do it in Trillian 3.free.

RSS

Subscribe to an RSS feed in Mail and you’ll know the moment an article or blog post hits the wire. Even better, you can choose to have new articles appear in your inbox.

I’ve never used an RSS reader, but I would love to get feeds as email.

Data Detectors

Act on information in Mail immediately. Mail automatically detects text fragments like appointments and addresses, and lets you choose smart actions with a click: create a new contact, map an address, or create an iCal event.

I want my entire life to be context sensitive. I want to right click ctrl-click on my bug queue at work and select the ‘fix’ option.

Time Limits and Bedtimes

Control exactly how much time your children spend with the computer each day. Limit total daily usage and define hours the computer can or can’t be used (set differently for weekdays and weekends). Built-in flexibility allows you to make adjustments on the fly as schedules and schoolwork change.

I would probably just set these for myself so I don’t stay up all night reading Digg and come into work late every morning.

Activity Logging

Keep an eye on your children’s computer activities. Leopard logs websites visited and applications used. It also maintains a list of people who have chatted with your child using iChat and a transcript of each text chat session.

I don’t have any kids, but this would probably be great for spying on your girlfriend/secretly gay brother.

This is great until the style overlap starts changing the context:

Merge All Windows

Combine all your open browser windows into one single, tabbed window.

Finally I can stop copy/pasting URLs to merge all those damn windows my IM and Email clients spawn.

Arabesque Screen Saver

Fill your screen with a multicolored, never-ending work of Arabesque art with the new Arabesque screen saver

I have no clue what this means, but it sounds sooooo sexy. Like a belly-dancer.

Tagging Downloaded Applications

Protect yourself from potential threats. Any application downloaded to your Mac is tagged. Before it runs for the first time, the system asks for your consent — telling you when it was downloaded, what application was used to download it, and, if applicable, what URL it came from.

Why didn’t I think of this shit (although to be fair, I’m sure Apple didn’t either)!

Guest Log-In Accounts

Allow anyone to surf the web and check email as a guest on your Mac. When they log out of the guest account, Mac OS X purges the account, removing any trace of their activity. So each time someone logs in as a guest, he or she gets a fresh, unused account.

“No mom, you can’t use my computer.”

Tabbed Windows

Keep multiple Terminal sessions going in a single, tabbed window.

I use PuTTY and sometimes I want just a few more features to make my life easier.

Wide Area Bonjour

Access your Macs, at home or on the road, with a single consistent host name. Use this host name whether you’re behind a NAT gateway or hopping across DHCP servers.

You mean I don’t have to use those random-ass dynamic IP services to connect to my home server anymore?

Ruby on Rails

Work in a developer’s dreamland. Leopard is the perfect platform for Ruby on Rails development, with Rails, Mongrel, and Capistrano built in.

The only reason I haven’t learned Ruby/RoR yet is because I’ve been too lazy to install it. Until then, PHP rulez.
