Apple's built-in screenshot app is pretty okay, but it's not quite seamless enough. When I want to file a bug report, or post a humorous screenshot to Flickr, or snap a screenshot to post on Technophobe, I turn to Skitch. Skitch has system-wide hotkeys, so it's just as convenient as the built-in Mac screen grab utility. It also has has the most crucial image editing features built right in, and when you're finished, you can even drag your image into an email or IM, or post your screenshot on the web with a single click. The Skitch interface is intuitive and just complex enough. You can't retouch a photo in Skitch, but resizing or cropping is a snap. Skitch sports a handy -- and relatively full featured -- editor. It takes just a couple of clicks to quickly crop or resize, and to highlight, annotate and scribble on your photos or screen grabs. I love the little touches with Skitch. Edits are never destructive. Everything can be undone, or deleted, or edited later. When post a screenshot it is saved to your history with layers, so you can come back later and remix things as you wish. Perhaps the best feature of Skitch is the integral upload capability. A single click posts your image to Skitch's own sharing service, or to Flickr, or to an FTP server you control. Once it's uploaded, one more click copies the link, all formatted and ready to paste in an email message or blog post. Skitch is a neat little package that captures my entire screen grab workflow from start to finish.

Don't get me wrong, I still use Skitch1 for quick and dirty screenshots and annotations. In fact, I use it more than Layers. But Layers gets my vote for coolest screenshot app of all time.

Everything. On. Your. Screen. Is. A. Photoshop. Layer.

Do I need to say anything else? Try it yourself, they have a free trial.

1. 1. The observant among you will note that I wrote this review before I wrote about Skitch. Isn't retroactive continuity great?

"Get a remote" is one of Seth Godin's Nine Steps to Powerpoint Magic. But what if you don't use PowerPoint?

Stage Hand is the ultimate Keynote remote. It shows you slide notes and previews, keeps a timer, and lets you jump around your presentation with ease. I used this app for my last presentation, and it made the whole thing not just seamless, but amazing.

Better than DDR. Better than Guitar Hero for Nintendo DS. Tap Tap Revenge is even two player so you can challenge your friends!

In my opinion, Tap Tap Revenge has done a great job of monetizing a free iPhone app. I'm not sure how their cashflow is, but I do love the subtle and appropriate integration of ads in this beautiful app.

Of all the sudoku apps in the App Store, this is my favorite. It's quick, attractive, and easy to use. It has really cute themes, too. It's the perfect subway app. Pull it out, play for a minute or two between stops, then quit or lock your phone. Your game will be right there when you get back.

This is too awesome. Simplify Media lets you access your iTunes library over the Internets, and even stream it to your friends. So you can listen to your favorite music from work or wherever you are. Plus, it's free.

Pandora radio almost makes mp3s obsolete. Thanks to the Music Genome Project, Pandora lets you make and train personalized internet radio stations that are catered to your taste, and recommends related music based on what it knows you like. You can even listen to stations created and shared by your friends.

With the Pandora iPhone app, you can access all the stations you already created at Pandora.com, and you can stream unlimited music to your iPhone or iTouch. Well, unlimited until your battery runs out.

Note: If Pandora gets shut down before you have a chance to enjoy this app, be sure to check out the iPhone streaming music player from Last.fm. It does a lot of the same thing, and looks like it might be around for a bit longer.

I really like getting things done1. And Appigo's ToDo is the perfect enabler. Not to be confused with the poser apps called To Do and To-do, Appigo's ToDo is the perfect balance of simplicity and functionality. It's easy to enter tasks, categorize, sort and check things off your list. With the latest release, ToDo has a "quick add" input, which makes adding tasks almost too easy. Best of all, ToDo syncs over wi-fi with Remember The Milk and Toodledo, so your to-do list isn't confined to your pocket.

1. 1. Note that it's the lower-case version of the phrase… There's nothing wrong with Getting Things Done, but it's a bit too structured and dogmatic for my tastes.

This is definitely one of the best free apps in the iTunes App Store: Apple's remote lets you take control of your entire iTunes library so you never have to get out of your LoveSac. The latest version even has full Genius Playlist support. :)

Have you ever noticed how hard it is to get to a calendar in OS X? Yeah, me too. You either launch iCal and wait for it to load, or you open the "Date & Time" preference pane and risk changing your time zone to Port-au-Prince.

And then you meet MagiCal by Charcoal Design. Not only is the name clever—MagiCal, Magical… get it?—it's a super useful app. MagiCal hangs out next to the clock until you need it, then jumps to life as a sweet little "month at a glance" calendar. It's packed with features, too. Clicking on a date will launch iCal and take you to the day's schedule. You can skip months, or jump to an entirely new date with a couple of clicks. If you want it for longer than a second or two, tear off the calendar and drag it around as a standalone window.

MagiCal can completely replace your system clock, if that's what you're into. It's crazy customizable, so you can make your date/time experience as complex or minimalistic as you want. MagiCal's bang/buck ratio is amazing. It has more features than you can shake a stick at, and it's absolutely free1!

1. 1. Like any free app, if you use it and love it, please support the developers so they can keep cranking out great software.

If you ever use more than one computer on the same desk, you need Synergy. Synergy is a protocol that allows several computers to seamlessly share the same keyboard and mouse. It's cross platform: I use it to control my Mac laptop, a desktop PC running Windows and a Linux box. I plop my laptop down on the desk, it automatically connects to my desktop computer, and I can use it just as easily as I would a second monitor.

The protocol is really slick. Once it is configured, move your mouse to the edge of the screen and the cursor jumps to the next computer. Keyboard control and window focus follow the mouse. It even shares your clipboard—you can copy something on one computer and paste it on the next. On most platforms Synergy can synchronize screen savers and sleep as well. Check out this quality illustration of the idea:

Image source: synergy2.sourceforge.net

Since Synergy is a protocol rather than a program, there are quite a few apps to use with it. I wouldn't use the official Synergy application on any platform other than Windows. Here are some great alternatives:

On a Mac, I recommend installing SynergyKM. It provides an easy to use preference pane, a graphical tool for aligning displays, and sweet keyboard remapping, so your ⌃, ⌥, ⌘ and Windows keys get along, no matter which keyboard or operating system you're using. It supports multiple profiles, so you can set your laptop up for home and work. It even claims to use Bonjour to automatically configure client computers1.

Get SynergyKM here

Linux configuration can get a bit tricky. The command line version gives you the greatest control, but takes a .conf file or two to get going. If you're not feeling up to that, check out QuickSynergy, a GTK 2 app that makes configuring Synergy a breeze. To automatically start Synergy when you boot up (or log in) check out this guide.

And for the unfortunate Windows users, check out the official Synergy2 application. It works great on anything >= Windows 95, so if your computer has a mouse you should be set…

1. 1. But that hasn't worked out for me yet. YMMV.

If there's one utility that should be installed on every Mac, it is Growl. Growl provides a unified system notification interface. By itself, it does nothing. But it allows all other apps to interact with the user in a clean and consistent manner. Growl is inherently Maclike, as it creates a consistent, attractive and unobtrusive way to let you know what's going on with your whole system.

Growl settings are almost too customizable, allowing each user to define exactly how notifications should appear and act. Notification styles range from small bezel windows to giant marquees to synthesized speech. Notifications can even be enabled, disabled or customized on a per-application basis. Check out some of the stock Growl themes. If none of those quite do it for you, choose from an extensive collection of third-party skins, or even create your own!

But just because you can tweak it doesn't mean you need to. Apps that use Growl "just work" out of the box. Once you install Growl you will be surprised how many of your applications already support it. The list of applications currently supporting Growl is huge: everything from download notices to incoming messages to update notifications are delivered via Growl. Growl "Extras" also exist for Mail.app, iTunes, hardware notifications1 and lots of other system apps.
