Why not, because we're current/former iPhone users and in all likelihood mac users as well.
I have a number of macs in my house, my wife as a iPhone 3G and I have a 3Gs.
While one of my earlier posts said to count me in as another iPhone user who's returning his N1 to google. I'm putting that on hold and I'm rethinking returning my phone.
As other stated, if you discount the keyboard, the N1 beats the iPhone on many fronts. Where it doesn't is apple's attention to details. Cut/Paste is the best example but there are others.
I love the iphone's approach, and yes it just does work, but I'm finding it a little too limiting.
Flash is coming shortly to android, I don't need to JB my phone to access features already built in. If I'm unhappy with my version of android, I can install a rom with those features. One word about jailbreaking, it seems fraught with headaches because when apple finally does provide a small update, like 3.1.3 it breaks the JBing. This cat and mouse game apple is playing is not evident with google. Root the phone and do what you want with it. Heck, I've read a thread on a forum that someone fairly easily installed debian on the SDcard of his android phone - how's that for getting your geek-on
