The nicer camera design is a huge thing to me. The iPhone 4 camera was already great for a phone and this upgrade pushes it one step further. And iCloud will make it so much easier to transfer photos and videos to Macs. The integration between devices in iOS 5 is a huge deal.
I've had the Siri app since before they were bought by Apple. It's really nice but I don't use it much because it's not that convenient to access, but now that it will be integrated into the OS and easy to get to, I'll definitely use it (whenever I get a new iPhone of course).
Oh yeah and the download speeds are really nice too.
