Here's cnet's review (literally just the first link I pulled from Google).

I don’t need to read a review. I owned one when they were launched, while I was working as an iPhoneOS developer. I would spend eight hours a day using an iPhone 3G and the rest of the time using my G1. They were roughly equivalent. The iPhone did some things better, the G1 did some things better. It didn’t take “several years” for Google to be in the same ballpark, they were in the same ballpark from launch, which was fifteen months after the original iPhone launch.
