I've got the standard Cingular-branded GSM RAZR, purchased shortly after they came out. Yes, indeed, the UI is horrific, but it's generally usable. The Motorola sync software was originally a very bad joke. Now it's merely a joke. Still, despite that, I'm happy with my RAZR. Why?
It's got astounding battery life. Even though it's over a year old, it's barely scratched. Sound quality is the best of any cel phone I've ever owned. The Bluetooth stuff works great. I can charge it with the USB cable attached to my computer (a mini-USB cable that came with a digital camera). As a basic phone, Motorola's hardware people outdid themselves. It's Moto's software people who need to be shoved out an airlock in deep space.
If my RAZR were to die a miserable death today, I'd probably go out and get another one, despite all its flaws. Now, if Moto would shoehorn some third-party software in the phone (Microsoft, Palm, Fisher-Price, doesn't really matter), then I'd upgrade immediately.
