Well, it's the first half of April, and for the past month and a half I've been using an 11" MacBook Air exclusively. I've also replaced my Droid with an iPhone 4S.
I'm beginning to feel a bit like an Apple snob, especially since my wife has an iPad and iPhone as well.
I had an iPod touch prior, so making the move to the iPhone wasn't that big of a change.
Moving to the MacBook though has been quite a change. Getting used to the key commands, and the desktop layout, but in the past 6ish weeks I've made the adjustment and like it.
Haven't spent a whole lot of time in XCode, but am hoping to.
