I constantly have to fight back the urge to buy more Apple products. It started in 2006 when I was in college and needed a new laptop for school. At the time, I had a great 12" dell that weighed about 3 lb and had an external optical drive. I ran FreeBSD on it. I needed a more powerful machine that ran Unix, and my friend badly needed cash, so he sold me his white macbook at almost 1/2 price. Since I knew that OS X has the BSD user land, I thought why not?
After a while, I understood why the Mac was so great. The power, flexibility, and stability of Unix with a wonderful graphical user interface and vendor support that made it a first-class citizen on the internet with regard to media sold me on OS X. I had that machine for quite a while until I traded it for an HP laptop that was more powerful. I ran linux on the HP for quite a while but got tired of fighting with the system to make all the goodies like card reader, camera, etc. work. I picked up a used 15" macbook pro and enjoyed having everything just work again. My wife got that machine, and I picked up a Dell laptop. Sold that and repeated the cycle with several more PC machines until I finally got a Unibody Macbook. That was the first one I used that really had gesture support. It was the gestures that hooked me.
We sold the 15" macbook pro, my wife got ended up with Unibody Macbook and still uses it almost three years later. I have bought and sold every size Macbook and Macbook Pro. I have settled on the 2010 11" Macbook Air as my personal machine due in large part to the screen and weight. I have also had the 24" iMac, but I prefer a laptop.
Now I don't even consider anything but Macs. My friend gave me an original iPhone and pays the bill, so I use it. I don't need a phone most of the time, but I like having the camera, apps, and phone all in one device. If the iPhone 5 works on T-mobile's 3G or 4G system, I might actually buy it and sign up for a data plan. I love the retina display and use my iPhone to read ebooks.
I have used the iPad from both generations. Not the device for me, but my wife and kids loved them. I was tempted to get an Apple TV, but I ended up getting a WD HD TV Live Plus ($100) because I don't have to have another computer on to watch my media stored on the USB drive attached to my Apple Airport Extreme Base Station (AEBS).
I actually tried three different high-end wireless-N routers from two different manufacturer's before buying the AEBS. I spent hours trying to get them to do everything I wanted. In the end, I returned them all, bought the AEBS and was ready in 5 minutes with exactly what I wanted. I am extremely impressed with the throughput on this router. I can copy data between my Macbook Air and the drive connected to the router at approximately 1 GB per minute which is pretty awesome for wireless.
I am intrigued by the combination of the newest Macbook Air with thunderbolt cinema display, but cannot justify spending that much. I am editing 1080p video now, so it would be nice to have a powerful 27" iMac to make that go faster/smoother.
I am not sure if I am addicted, but I definitely have the desire to buy some of the newest apple kit because it works well for me.
