I am with the OP, sadly. I started my foray into handheld Apple devices with the 1st gen iPod Touch shortly after it was released. Then I got the iPhone 2G. In January I got the iPhone 3G, and in June I got the iPhone 3GS. Are they great devices? Absolutely. Are they entertaining? Absolutely! Do they keep me satisfied with my mobile computing? To an extent. Why?
The UI. It hasn't change much at all since the 1st gen iPod Touch came out. You turn the device on, see a wallpaper, text-based date/time, and an unlock slider. Unlock the device and you have icons thrown at you. I am a fan of the welcome screen on some devices. I thought the MotoQ (despite being a Microsoft Smartphone) had a great welcome/home screen (or all WinMo 6.1 devices for that matter). The wow factor of WinMo ends at the home screen, but damn is the home screen nice. Same goes for Android. The G1 has a nice home screen, you can pull up the full App list, or pull down the notification area, but to begin you have a nice home screen. THAT is what I like.
Maybe I do have a short attention span. I am 21, I can pay attention just fine in school. Is technology different? Technology is rapidly evolving every single day. New devices are being introduced daily sporting new UI's. The iPhone/iTouch (I don't care if some people hate the name iTouch) UI has remained unchanged. Sure you can jailbreak and change the themes and looks of the icons, but BIG DEAL. That isn't the point. Change the icons all you want, the overall UI remains the same. It is VERY functional, but getting stale.
How do people like me combat the boredom that comes with owning technological items? Well I work with technology every day. We order new servers and systems frequently so the fun never stops from that angle. On my personal phone side, I own two phones. The iPhone, and a MotoQ (broken sadly). When I get bored with one, I switch to the other. Then back. Some days I want a physical QWERTY, other days I want my iPhone. Bored with one? Switch to the other.
In my life and at work, I constantly see technology changing. New servers are released with more memory and faster processors. Constantly patching Linux servers to remain ahead of the hackers. Yet the mobile device that is a huge part of my life remains the same. That is why I switch phones every now and then. To mix things up in my constantly changing technological life. How can you expect me to deal with the constant change in technology at work and yet never change my technology on a personal level?
That was a rant.
