I don't collect iPhones, but like your idea. I plan to collect smartphones in general. One with a different OS so the experience will be different. I even want an old WinMo phone like the Xperia X1. Collecting iPhones is great just like people who collect iPods, but probably gets too expensive or redundant. I prefer if I collect it, I need to use it and not watch it collect dust. With specific smartphones, you can always use it and it offers a different experience. But whatever makes people happy. My plan for 2012 is to use my iPhone 4 as an iPod touch, my Pixi+ as a compact mp3 player, and then rotate between a BlackBerry, N9 (MeeGo), Xperia Play or Nexus One (Android) Xperia X1 (WinMo), and Samsung Focus (WP7) next year. My next MAIN phone will likely be a BlackBerry QNX phone in 2012 once my contract is up with iPhone 4. Use one for each week when I go to work. An X-Men of phones. If I collected all iPhones, I will likely end up keeping the SIM in the most recent one. Why downgrade, right? The advantage is collecting iPhones keeps you in the same ecosystem. I prefer a variety of brands although the outlet can get messy with a variety of charges and you have to install different software. But I prefer learning different things similar to people who collect cars. The manufacturer is not always the same.
