I got caught in the gravity well of the Halo effect with the iPhone. I wanted one badly and in order to convert my wife, I replaced her Palm Tungsten W with an iPod Touch 2nd-Gen to get her used to it. A few months later she told me how much more useful the iPod touch would be if it was also a phone. We both got the iPhone 3GS when it released.
After the iPhone purchase I replaced my network setup with an Airport Extreme with two satellite Airport Express units extending the network -- at the time it was the only router that would do WPA2 with wireless network extension. Later I sold one Airport Extreme and Express to my sister-in-law and my current setup has 3 x Simultaneous Dual-Band Airport Extreme (2 satellite ones extending the network) and one of the original Airport Express for AirTunes (now AirPlay).
In addition we replaced our 7-year-old Dell PC's with 27-inch iMacs and got our children a Mac Mini. I bought the first generation iPad, used it for a year, then sold it to my sister-in-law and bought the iPad 2.
The total hardware purchases from Apple since that first iPod Touch have been:
- 2 x iPhone 3GS (now sold)
- 4 x Airport Extreme (1 now sold)
- 2 x Airport Express (1 now sold)
- 2 x iMac 27-inch
- 1 x Mac Mini
- 1 x Apple TV G1
- 1 x iPad (now sold)
- 1 x iPad 2
- 2 x Apple TV G2 (one recently bought and given as a gift)
- 2 x iPhone 4S
- 2 x Magic Trackpad (one bought as a gift)
- 3 x iPod Touch 4G (used, bought for Christmas gift to kids)
My sister-in-law who bought all but the used iPhone 3GS from me has purchased:
- 1 x iPhone 3GS
- 1 x iPad (from me, as a gift to her fiancé)
- 2 x Airport Extreme (1 from me, 1 newest from Apple)
- 1 x Airport Express (from me)
- 1 x 15-inch MacBook Pro
- 1 x iPhone 4S
So I would say that one little iPod Touch G2 purchase has snowballed into quite a bit more. We still have that iPod Touch G2 which has a cracked screen with a piece of scotch tape over the crack. The kids play with it. This Christmas they will each get an iPod Touch 4G to replace it. Then that original iPod Touch will become a dedicated remote control for the Apple TV2.
