Ive had a iPhone since the 3G and I love it, I have no desire to buy a Macbook or any Mac computer unless I'm going to be doing some hardcore video editing, photoshop etc. The one button does a lot of different things that you can set to what you want. If you have the phone open hit the home button and it goes to your first page of apps, hit it again (or if your on the first page to begin with) and you get a search function. My GF has a incredible 2 and we keep finding this that hers does that mine doesn't and vise versa its all about what you want.
