All day on December 25, TUAW presents "Now What?" We've got first steps and recommendations for all the Apple gifts you (hopefully!) found under the tree today. Happy holidays! If you're a Mac veteran, send a link to this post to the switcher on your holiday list.

Merry Christmas, new Mac owner. First of all, congratulations! Welcome to the family. There's some eggnog on the table, and feel free to put your coat on the bed. Setting up your new Mac is a famously easy experience. It should take about 10 minutes, depending on the kind of Mac you bought, and where you want to put it.

Once you have your new Mac on your desk, it will take you through a short setup process to personalize your new machine. You'll choose a username, a password, and will be given the option to register your Mac and sign up for MobileMe, if you want. (You can register and sign up for MobileMe later, if you don't do it now.)

If you bought any applications along with your Mac (like Microsoft Office, for example), you can install them very easily. Just insert the disc, and either drag the application to your Applications folder (on your hard disk) or double-click the installer application. You can eject the disc when you're done by dragging it to the Trash, or pressing the eject key on your keyboard.

For Windows compatibility, get your Windows XP (SP2 or SP3) or Windows Vista disc ready, and double click the Boot Camp Assistant in the Utilities folder (it's inside your Applications folder). Boot Camp Assistant will walk you through the process of installing Windows on your Mac. It's not difficult, but it will take a little time. Once Windows is installed, you can hold down the Option key before your computer boots to choose which operating system to run, or select a permanent preference via the Startup Disk pane of System Preferences. You can read more switcher-specific tips in our Switchers category.

If you're switching to the Mac platform from the PC, I might humbly suggest you read Part 1 and Part 2 of my experience introducing my dad to the Mac. He was a hard-core PC user until he fell in love with his Mac mini.

If the favorite people on your holiday gift list spend more time in hotels and airports than they do hanging out with you, then we can help. This guide to gifts for the frequent traveler is sure to put a smile on the face of your friends or loved ones wherever their travels may take them in 2009.

Power on the go
With rare exceptions, it's almost impossible to find an airport or hotel room with enough power outlets for all of your electronic gadgets. Rather than challenging someone to a duel with presentation laser pointers to see who gets to use the one available airport outlet, I've come up with a more peaceful solution -- carrying a compact multiple outlet with me.

Belkin's Mini Surge Protector with USB Charger (at right, above) can handle three AC and two USB devices simultaneously. It's tiny and light, and fits just in just about any laptop case.

My personal favorite is the Monster Cable Outlets To Go Power Strip (below), which fits six widely-spaced grounded AC outlets in a very flat 8.5" x 2.25" x 1.8" box. This one works very well with those obnoxious adapters that cover two or three outlets by themselves, and is perfect for sharing a single power outlet with five total strangers. If more people carried these in their laptop cases, there would be world peace...at least in airports. It's also available in even more compact 3 and 4 outlet models.

If you use Time Machine in Leopard, then transferring your stuff to a new Mac might be a bit simpler than you thought. With Migration Assistant, you can easily transfer Applications, Documents, Settings, and more. In this Mac 101, we're going to show you how it's done, and how you can do it yourself!

1. Make sure you have a recent backup
Make sure you have a recent Time Machine backup on the machine you wish to transfer your information from. To check, go to System Preferences (Apple menu) > Time Machine. If you see a recent backup, then you're set; if not, click "show Time Machine status in the menu bar." In the resulting menu bar item, click "Back up now." Time Machine will make a new backup.

2. Make sure you're not leaving anything behind
In the Time Machine System Preference pane, click the Options button. In the dialog box, you can see all the folders you have chosen not to backup -- check these to make sure you really don't want them. If you do, click the folder and chose the "-" (minus button) at the bottom. Click OK and backtrack to step 1 to create a current backup.

3. Getting the new machine ready
From this point, you can deviate into two directions:

• If your Mac is new: Boot up the new Mac and go through the setup screens. When the setup assistant asks if you want to migrate information from your old Mac, choose "From Time Machine backup or other disk."
  
• If your Mac has an existing account, don't fret. Just open "Migration Assistant" located in /Applications/Utilities.
  

4. Connecting your Time Machine drive to the new machine
Once you have completed the above step, click continue. Migration Assistant will ask you to specify the backup you would like to transfer to the new machine.

jarpy has an interesting post up on installing Windows XP to an external USB hard drive without using Boot Camp to repartition his internal drive. This method makes use of the Open Source rEFIt utility which we've mentioned before. The process itself looks somewhat risky (e.g. jarpy disconnected his internal drive to avoid corrupting his OS X install) and playing around with third-party boot loaders is always potentially dangerous in my opinion. However, the payoff of a USB-bootable Windows drive is rather appealing, so it might be worth a look for some of you. Proceed at your own risk. If any of you decide to get this working, please share your experiences in the comments.
