The reason I am going into mac is primarily because of y mother's purchase of an iMac (20"). It literally took me about 15 minutes to set up the iMac, create a 802.11n network, start backing up the iMac's contents to a wireless hard drive, set up a printer through the Time Caspule (and begin printing stuff from my PC upstairs wireless, as well as from the Mac), and create my mom's itunes library and sync her iPod to it.
Furthermore, I am a minimalist in design, so the entire Mac product line is perfect. The iMac has no codes on the front, no buttons or labels, just one black apple on the beautiful brushed aluminum. The mac is designed to be as wireless as possible, built in bluetooth and wifi. I already own the apple wireless keyboard even though I use a dell because I love it so much.
Yes, I know that mac have problems like PC's, I know they are not invincible, but they are considerably less bloated, have virtually no viruses even coded from them, and are designed to be simpler.
