(Other than the size of the screen, the 15-inch model is the same as the 12-inch one.)

SOFTWARE
The computer comes with some great software. iTunes is the best media player on the market. I have almost 5,000 songs stored on mine. With the search function and browser display, it is easy to find a particular song. iTunes also keeps track of the number of times you've listened to a song and it allows you to rate your songs. It's easy to create a playlist. Also, burning one of those playlists onto a CD can be done with one click.

Safari is a great web browser. It has a Google search box built into the toolbar, prevents pop-up ads (I've never had one), has tabbed browsing (preventing a cluttered desktop), and allows for bookmarks to be added with one click.

iChat allows Mac users to customize their AIM and Rendezvous chat sessions in ways that the normal applications don't allow, such as adding pictures from iPhoto to their profile.

I haven't mastered iPhoto yet, but it is downloading pictures from a digital camera is as easy as plugging it into the USB port and clicking a button.

Also, Macs are less likely to get a virus or be overtaken by spyware.

The iCal and Address Book look good, but if you are going to sync a PDA with your Mac, you are better off using Palm Desktop software. Hopefully the functionality of those programs will be improved in the future though.

Finally, most of the programs work with each other. For example, if someone on my iChat buddy list is online, a green dot will appear next to a message from him or her in my Mail inbox.

I also use Microsoft Office, Quicken, Dreamweaver MX, and Palm Desktop - they all work well on the Mac. Office shares files perfectly with PCs.

HARDWARE
Spend the money and get the superdrive (CD-RW/DVD-R). DVDs have more memory than CDs and blank DVD-Rs are becoming more affordable. If you are into collecting videos of concerts, a DVD-R is a must.

I'd recommend upgrading to at least 768 MB of memory and the 80 GB hard drive. Burning a DVD requires a lot of memory and can take a while - this way you can use other applications while burning a DVD (on my old PC, if I was burning a CD, I couldn't use anything else). The hard drive space is really cheap. Plus, if you load your CDs on your computer, they can eat up a lot of memory, even as MP3s (my 5,000 songs take up about 25 GB).

Also, there is a lot to be said for getting the Airport Exteme card (although you can buy a third-party base station for less). I am able to browse the Internet in any room of my house - well worth the extra $100 or so.

I have the 12-inch monitor, but that was because Apple hadn't released the 15-inch in the new style when I made my purchase. The 12-inch is fine - it's much clearer than my old PC notebook - but if I had the opportunity, I'd probably go with the bigger monitor.

DRAWBACKS
-While most software is available for Mac OS X, there are some programs that aren't (Google toolbar, Yahoo! toolbar, Kazaa, AvantGo) or minor problems in software that is available (Quicken can't access accounts on Ameritrade via Macs)
-The PowerBook doesn't have a fan, which is great for the battery, but can cause it to get a bit hot underneath where the user rests his left hand.

Regardless of those drawbacks, however, buying a Mac was an easy decision. If you have any questions about it, click on my profile and send me a e-mail.

UPDATE: After 14 months, the hard drive started making noise and system performance got slow and I couldn't run as many programs as I used to. I called Apple and had to spend $300 for them to put in a new hard drive and some other hardware. They were unable to transfer my data to my new hard drive, so I've spent the past four days reloading all of my software and applications. No idea why the hard drive went. Hence I dropped the rating from five stars to four.

Portability is superb - it's thin and light. and as a prior review said, the attention to detail in the design is unmatched. The keyboard is wonderful, and the screen is a knockout. The sound is okay, but I don't expect a notebook - especially one that's an inch thin - to blow me away. The power pack is about 1/3 the size of a Dell, which is very nice when you're taking it on the road. Further, the connectivity rules - firewire 400 and 800, USB 1 and 2, and DVI out. Plug in a second monitor, and you can span displays, no sweat. (Have your email open on your PowerBook screen while you use applications or surf the web on a second monitor.)

The operating system is rock-solid, and multi-tasks far more smoothly that any Windows system I've used, and I've got a pretty kickin' Windows desktop machine. Also, this machine has not crashed on me once (or "flaked out" even) since I've owned it, and I use it 10 hours a day, every day. After using the PowerBook for the last few months, I've decided I will never be without one.
