The Unarchiver is designed to handle many more formats than Archive Utility, and to better fit in with the design of the Finder. It can also handle filenames in foreign character sets, created with non-English versions of other operating systems. I personally find it useful for opening Japanese archives, but it should handle many other languages just as well.
It is very simple to use and install - simply copy it into your Applications folder or whereever you prefer, and then set archive filetypes to open using it. This can either be done the usual way, or by double-clicking the icon to show The Unarchiver's preferences.
Supported file formats include Zip, Tar-GZip, Tar-BZip2, RAR, 7-zip, LhA, StuffIt and many other old and obscure formats.
IconBox is an iPhoto like application that enables you to store, manage & change your icons or dock using simple drag & drop like functionality which has been seamlessly integrated into our new "Box" system.
Very similar to CandyBar from Panic, but it works with Lion and is imho more easy on the eye.
Since i have to stay a while on my late 2008 13'' MacBook before i can buy a new i7 MacBook Pro, i decided to tune it with a brand new Intel SpeedStar 120GB SSD and a fresh Installation of Mac OS X Lion Developer Preview 4.
After a little downtime the Apple Developer Center is back and iOS 5 beta is ready to download!

Syncing your digital data is getting harder and harder with more devices and more content to manage. In the past the Mac/PC was the digital hub but today it's just another devices.
Now the iCloud gonna be your new digital hub (for the cloud haters: you can stay with your pc/mac as hub) and takes care of syncing and pushing your content to all your devices. Also iCloud can be integrated in any application (a new api:3) making it possible to sync data of all applications that support it.
Change your calendar, contacts, photos on one device and the data gets updated on all your other devices automatically.
It's fully integrated in the AppStore, iBooks and iTunes,
buy once and use it on all your other devices (no extra costs)
Notifications are no longer modal, not interrupting and just appear as a bar on the top of the screen and fade out after a while. They appearatnly took the style from Mobile Notifier a jailbreak extension. (they hired the developer).
A swipe on the top bar (like for SBSettings) brings up the notification center a unified place showing weather, new notifications,sms etc.. it kinda looks like the Lock Info jailbreak extension.
There is also a way better lock screen with all features of the notification center and widgets
They showed gestures for switching to full screen and back.
Photo Booth has full screen mode and new effects, expect twitter birds.
In depth preview of the auto save and Versions feature.
AirDrop peer 2 peer file exchange over WiFi, its already available in the beta builds will write in depth about it soon.
Mac OS X Lion will be released in July for 29,90$ only on the Mac Appstore.
BootXChanger will allow you to change the boot image and background colour on Mac OS X 10.4, 10.5 and 10.6. I had no time to test it on Mac OS X Lion yet (currently on a trip) so use it on your own risk on 10.7.
The usage is straight forward and some sample images are included as well.
Limitations If your image has transparency, it will be redrawn over the background colour before being applied, so save the original somewhere in case you want to change the background colour later.
Some macs will scale big images down when booting, or ignore the image if it's really big. Others will happily accept a full-screen image.
If you have a PowerPC Macintosh, you can use BootXChanger 1.0.4, which you can still download from namedfork.net/booxchanger.
Simple, realy useful, tool i use daily to stop my MacBook from going to sleep-mode.
Caffeine is a tiny program that puts an icon in the right side of your menu bar. Click it to prevent your Mac from automatically going to sleep, dimming the screen or starting screen savers. Click it again to go back. Right-click (or ⌘-click) the icon to show the menu.
