If you're looking for the definitive comparison table between the Google Nexus One, Apple iPhone 3GS, Motorola Droid, and Palm Pre, here you have it. From storage capacity to price to plans. Guess who wins (you'll probably be wrong).
My impression is that nobody clearly wins. Each of these phones have their own strengths and weaknesses, but there's still not a definitive one. My favorite is still the iPhone just because the user interface design and the amazing applications—it's not the number, but when you have 126,000 apps, inevitably you are going to have some amazingly good apps in each software category. However, in terms of specs, things are not that clear at all. At the end, it's still a matter of personal preference. [Billshrink—Thanks Ricky]
