Here's the Win/Fail count by item:
Firmware 2.0: Win. Many operations (like using the Photo app with my 8.5kPhoto library) are faster. Mobile Safari protects from ad pages and pop-ups better, but crashes more often on really complicated stuff. Contacts search is huge. This Win pretty much balances out all the Fail awards, it's so big.
Battery life: Possibly Fail. I had push on for my Exchange-ish account (I use Kerio Mail Server 6.5 at work), but after the first day of normal usage, for some reason last night it caught in a loop or something and drained half my battery in about an hour. I assume a bug. Until I figure it out I went back to timed download. If push does this regularly then battery life gets a Fail, but still no Win unless 3g life turns out good.
AT&T 3g - Fail. 3g speed rocks, but often I find myself unable to get any bars of 3g. And the phone has some trouble switching back and forth. Indications online appear to be that this is an AT&T issue - they had similar capacity problems the first week or so after iPhone 1.0. So for causing the same issues two years running AT&T gets a bag full of Fail.
GPS: Win. Works well, locks quickly, and is pretty simple. Well-integrated with Maps.
Form factor: Big Win. The 3g is more comfortable in the hand and slides into a pocket better. The new speakers are clearly better. The buttons are even better, and the headphone jack is normal.
Activations: Massive, unprecedented Fail on day 1. Not so bad now. Apple worked around the worst of it, thankfully, and I got mine activated without too much trouble once I made it home.
Peripheral compatibility: Win, but the Firewire loophole is now shut. Until this model, you could use older Firewire-based chargers to charge iPhones. No more. Otherwise, compatibility is good.
Capacity: Win. 16 GB is mega-useful. My old one was full.
As with the old model, expect a minor firmware update to be distributed in 2-4 weeks that fixes the vast majority of the issues I and others notice. Despite the things I've dinged here, overall there is a lot more polish on the 2.0 phone than was on the 1.0 at initial release. That's important. And the App Store is awesome. I can't even do justice to it in this post.
