After just a few months of suffering on the iPhone, I went with a BB Pearl, which was hardly better app-wise but much better as a communications device overall. As soon as the N900 dropped I bought one at full price and I was back in smartphone nirvana. Of course, by then Android phones had hit the scene and the iPhone had vastly improved, and the N900 started feeling slow and cumbersome compared to my coworkers' and friends' devices.
Later my love for the Nokia device transferred to Windows Phones, which I still maintain were the best smartphone paradigm ever made. For once I felt Microsoft finally "got it right" on the OS design and people-centric interface. I sorely wish they still made phones with mobile Windows 10, but I get why they left the market.
