And here is my stability report: 1. Not a single total system crash or lock-up. (my Treo use to lock up twice per day no matter how many full system resets I did.) 2. Not a single incident with the phone other than a dropped call or two in bad coverage areas. (Treo had so many phone related issues it was maddening) 3. Safari is amazing and stable. (Bring on Flash and Java please) 4. Email works great and pdf's, MS Word and Excel files view beautifully. 5. The iPod is super and video capability is equally great. 6. There are many details described all over the internet that will bolster the power of the device, but I'm VERY pleased with my iPhone. I'm sure there are some power users out there that have beat their iPhone my than I, but my 20 + hours have been stellar.
