Exactly why when I upgraded, I just got the Droid X instead. I toyed with the concept of switching to the iPhone 4, but thought better of it for just this reason.
I don't need to game on my phone... but after rooting it, installing the free Wi-Fi hotspot apk, and deleting all the bloatware, I couldn't care if the next phones are quad-core-8Ghz, Nvidia 580GTX (GTI, GTS, GTGAY, whatever) graphics, etc.... I'm completely happy with what I have: a great, smooth-running phone that does everything I need it to do... take calls, send email and texts, take some good pictures, act as a WIFI hotspot (iPhone can't do this), and browse the web from time to time.
