In a Q3 earnings call on Tuesday, Apple said third-quarter profits rose more than 77 percent largely from the success of the iPad and iPhone 4--probably not a big surprise for anyone. But the more shocking announcement (in my eyes) is that Apple set a record for the most Macs they've ever sold in a quarter with 3.47 million.

Obviously, I've always been a big fan of Mac computers, but I guess with the emergence of handheld devices like the iPad, iPod, and iPhone, I figured Apple's desktop and laptop business would not be as strong as it once was. Perhaps all these new iPhone users are deciding to give Apple computers a try. Whatever the case is, I'm glad to hear Mac computers are still selling well.

If you're one of the people who recently picked up a Mac (apparently there are quite a few of you), check out our Mac Starter Kit for some must-have software you can download right away.

If you're an iPhone user, make sure to come back and check out this week's apps, which include a simple free to-do list app and a platform game that challenges you to dig deep into the depths of dangerous mines.

SeizeTheDay isn't the most full-featured to-do list app at the iTunes App Store, but as a free app, it offers just enough tools to make your daily tasks much easier. The simple interface of SeizeTheDay makes it easy to navigate so you can get to your list in only a couple of swipes of your finger. The app offers local notifications so you'll get reminders of your daily tasks even if you don't have an Internet connection. SeizeTheDay also takes advantage of iAds (it is a free app, after all), but the ads showed up infrequently in my testing and never got in the way of using the app.

SeizeTheDay lets you quickly create tasks with fields available for setting the due date and priority, along with notes about the task and the capability to set up a reminder. The Home screen in SeizeTheDay divides up your tasks so you can view items that need to be done today, upcoming tasks, and tasks that need to be done "at some point." A tagging feature lets you quickly get to all tasks tagged "Work" (for example) so you'll be able to quickly get to lists that revolve around a specific subject. Overall, SeizeTheDay has just enough features to make it a very useful to-do list for anyone trying to stay organized.

Miner Disturbance

Miner Disturbance is a fun mining game that will immediately remind you of arcade classic Dig Dug, but offers much more. The object of the game is to complete goals as you dig downward into each mine. Some goals will require that you collect a certain number of minerals, while others will only require that you've dug to a specific depth.

But as you dig your way deeper, you'll face baddies like moles, bats, and other underground dwellers that you'll be able to defeat by swinging your pick. As you go further into the game, you'll face water-filled caverns forcing you to go up for air, and hot lava that may mean certain death. All this adds up to plenty of variation on the digging mechanic and remains exciting for me even after several days of playing.

Miner Disturbance lets you navigate from mine to mine by tapping on circled locations on the main map or, if you have collected cash rewards, lets you buy better mining equipment at the above-ground store. The controls are a bit tough to get used to at the start (as any touch-screen directional systems tend to be), but quickly become second nature as you dig deeper into the mines.

Along with the main map, which features several mines, all with different goals, Miner Disturbance includes a second snowy map where you'll face different challenges and a Volcano mine where you can compete for the high score with other players online. Overall, if you're looking for a game with a little more depth (yes, I know: intended!) than Dig Dug and some light RPG elements, Miner Disturbance is a steal at 99 cents.

What's your favorite iPhone app? Are you surprised at the continued success of Mac computers even as the iPhone steals all the limelight? How do you like the feature set in the free SeizeTheDay? What's your high score on the volcano level of Miner Disturbance? Let me know in the comments!
