While I like the Mac, and I sometimes find SJ over the top in his over-enthusiasm with devices in the past few years, his statement of the majority of Apple's revenue and income from devices seemed suspect. But if the hype and lines of people are any indication of the up 80.3% percent quarterly revenue (Macworld, WSJ, and others) of iDevices for Apple, iPad2 will only increase that margin. He may use the term, "post personal computer" regarding the iPad, but this time I think he's right.
For the devices, I think this is great news, and while the launch presentation was SJ at his very best, I don't know what this does for the future of Mac as we know it. It appears iPad can eventually morph into the chief computer product for Apple and if it gets OS X, be the next generation mobile computer for them.
I think Garage Band and iMovie, at five bucks extra, the great magnetic cover, the low price in this recession, as well as HDMI capability, give this product a worthiness to have lines outside the store far beyond the MBP refresh.
