I switched to an IMac from my DELL XPS and it was a decision I do not regret.
First, the fact I have ONE CHORD. ONE, UNO, 1. Not 50. The keyboard and mouse are wireless and so is the printer. I hooked up a Time Capsule that serves as a router and backup device. It took minutes to set up and use. I clicked one button on each MAC (two Mac Books and the I Mac) and it synced them, set up the back up schedule and had me online. It was not rocket science on settings and installing programs and troubleshooting everything. The ease of everything to me is like night and day. I never took the time to go thru the steps to set up a network with my DELL and TOSHIBA laptops. With the Mac it took one click and all of a sudden everything in my house was synced and able to share files, etc.
The fact it is a MAC OS, MAC CPU, MAC keyboard, etc etc makes my life easier. If I had problems with installing VISTA I called Microsoft. They sent me to DELL. In the end they were on 3 way blaming each other on why it would not work. The tech support from Mac is amazing and very professional.
Oh yeah, and for all my Windows based stuff, clicking the Boot Camp icon allowed me to set up Vista on my Mac on some of the available space. There is software where I can jump from Mac OS and Windows with a click.
Toss in how Apple deals with everything. I did my rebate online. No UPC, no mailing, no forms. I went to their web site put in my receipt # and it told me the amount I had coming and processed everything. I can make appointments at the Apple Store online and actually deal with someone who knows what they are talking about.
Not putting any Apple stickers on my Caddy anytime soon, but I am officially a Mac customer now.
This is the complete CPU below. Mine came with the wireless keyboard and mouse, so picture even those chords not there:
