Here are five quick, random observations based on about 10 minutes of fiddling with the iPhone after activating it.
1. Typing in passwords, especially long ones, is a pain. Just as in Safari on your Mac (or, ahem, PC), when typing in passwords, all you see are dots for the characters. When you're getting used to the iPhone's soft keyboard, typing in passwords can be an exercise in frustration, especially when you type the wrong character, have to clear it, then forget where you are in the password, usually leading to the need to start from scratch. At least, with Wi-Fi access, it works the same as connecting on a computer: You only have to type the password in once, even if you leave Safari to do other things on the phone.
2. Browsing takes a little getting used to and feels a bit awkward at first. But text is surprisingly easy to read, especially since you can resize it at will. When we clicked on a link on CNN's website that required Windows Media Player, we encountered a "plugin warning" and couldn't figure out any way to go back to the page we'd come from, except to go all the way back to the original bookmarks folder for News.

This is what I got when I accidentally chose a link that required Flash or some other plug-in on CNN.com. (P.S. The phone and the screen look MUCH better than they do in this photo. It's late, and I didn't feel like messing with the camera to get the perfect shot. If you know of a screen grab utility for the iPhone, please let me know!)
3. The keyboard really is pretty damn smart. I typed "iswf" and it somehow knew I meant "used."
4. Viewing files attached to emails (like Word, etc.) is faster and easier than it is on a Mac. Really.
5. Sometimes the accelerometer doesn't work with email messages and Web pages - at least not right away. (And, of course, it only works in one direction, counter-clockwise to switch from vertical to horizontal and clockwise to switch back.)
